The Saitek X65 joystick has a pair of axes that were used as mouse pointer controls by the Windows driver. The corresponding usage page is the Game Controls page, which is not recognized by the generic HID driver, and therefore, both axes get mapped to ABS_MISC. The quirk makes the second axis get mapped to ABS_MISC+1, and therefore made available separately.

This mouse has a horizontal wheel that requires special handling. Without this patch, the horizontal wheel acts like a vertical wheel.
In the output of `hidrd-convert` for this mouse, there is a `Usage (B8h)` field. It corresponds to a byte in packets sent by the device that specifies which wheel generated an input event.
The name "A4TECH" is spelled in all capitals on the company website.

HUTRR101 added a new usage code for a key that is supposed to invoke and dismiss an emoji picker widget to assist users to locate and enter emojis.
This patch adds a new key definition KEY_EMOJI_PICKER and maps 0x0c/0x0d9 usage code to this new keycode. Additionally hid-debug is adjusted to recognize this new usage code as well.

In hid_submit_ctrl(), the way of calculating the report length doesn't take into account that report->size can be zero. When running the syzkaller reproducer, a report of size 0 causes hid_submit_ctrl) to calculate transfer_buffer_length as 16384. When this urb is passed to the usb core layer, KMSAN reports an info leak of 16384 bytes.
To fix this, first modify hid_report_len() to account for the zero report size case by using DIV_ROUND_UP for the division. Then, call it from hid_submit_ctrl().

It's theoretically possible for the runtime PM reference to leak if the code fails anywhere between the pm_runtime_resume_and_get() and pm_runtime_put() calls, so make sure to release the runtime PM reference in that case.
Practically this will never happen because none of the functions will fail on Tegra, but it's better for the code to be pedantic in case these assumptions will ever become wrong.

[ Upstream commit 0cfe5a6e758fb20be8ad3e8f10cb087cc8033eeb ]
In some cases we may need to initialize the host1x client first before registering it. This commit adds a new helper that will do nothing but the initialization of the data structure.
At the same time, the initialization is removed from the registration function. Note, however, that for simplicity we explicitly initialize the client when the host1x_client_register() function is called, as opposed to the low-level __host1x_client_register() function. This allows existing callers to remain unchanged.

Before registering the SOR host1x client, make sure that it is fully initialized. This avoids a potential race condition between the SOR's probe and the host1x device initialization in cases where the SOR is the final sub-device to register to a host1x instance.

The current control flow of IRQ number assignment to `irq` variable allows a request of IRQ of unspecified value, generating a warning under Clang compilation with omap1_defconfig on linux-next:

Before this patch, gfs2 would deadlock because of the following sequence during mount:
mount gfs2_fill_super gfs2_make_fs_rw <--- Detects IO error with glock kthread_stop(sdp->sd_quotad_process); <--- Blocked waiting for quotad to finish
logd Detects IO error and the need to withdraw calls gfs2_withdraw gfs2_make_fs_ro kthread_stop(sdp->sd_quotad_process); <--- Blocked waiting for quotad to finish
gfs2_quotad gfs2_statfs_sync gfs2_glock_wait <---- Blocked waiting for statfs glock to be granted
glock_work_func do_xmote <---Detects IO error, can't release glock: blocked on withdraw glops->go_inval glock_blocked_by_withdraw requeue glock work & exit <--- work requeued, blocked by withdraw
This patch makes a special exception for the statfs system inode glock, which allows the statfs glock UNLOCK to proceed normally. That allows the quotad daemon to exit during the withdraw, which allows the logd daemon to exit during the withdraw, which allows the mount to exit.

The GLF_LRU flag is checked under lru_lock in gfs2_glock_remove_from_lru() to remove the glock from the lru list in __gfs2_glock_put().
On the shrink scan path, the same flag is cleared under lru_lock but because of cond_resched_lock(&lru_lock) in gfs2_dispose_glock_lru(), progress on the put side can be made without deleting the glock from the lru list.
Keep GLF_LRU across the race window opened by cond_resched_lock(&lru_lock) to ensure correct behavior on both sides - clear GLF_LRU after list_del under lru_lock.

For instance, ip=::::myhostname::dhcp will use "myhostname" rather than ignoring and overwriting it.
Fix the comment on ic_bootp_string that suggests it only copies a string "if not already set"; it doesn't have any such logic.

[ Upstream commit 33f409e60eb0c59a4d0d06a62ab4642a988e17f7 ]
A few weeks ago, we saw a two cursor issue in a ChromeOS system. We fixed it in the commit:
drm/amd/display: Fix two cursor duplication when using overlay (read the commit message for more details)
After this change, we noticed that some IGT subtests related to kms_plane and kms_plane_scaling started to fail. After investigating this issue, we noticed that all subtests that fail have a primary plane covering the overlay plane, which is currently rejected by amdgpu dm. Fail those IGT tests highlight that our verification was too broad and compromises the overlay usage in our drive. This patch fixes this issue by ensuring that we only reject commits where the primary plane is not fully covered by the overlay when the cursor hardware is enabled. With this fix, all IGT tests start to pass again, which means our overlay support works as expected.

[ Upstream commit a8db57c1d285c758adc7fb43d6e2bad2554106e1 ]
The error code is missing in this code scenario, add the error code '-EINVAL' to the return value 'err'.
Eliminate the follow smatch warning:
net/core/rtnetlink.c:4834 rtnl_bridge_notify() warn: missing error code 'err'.
