[PATCH] drm: radeon: ci_dpm: Add error handling in ci_enable_vce_dpm()

by Wentao Liang

The ci_enable_vce_dpm() calls ci_send_msg_to_smc_with_parameter() but does not check the return value. A proper implementation can be found in the ci_upload_dpm_level_enable_mask(). Add a check after calling ci_send_msg_to_smc_with_parameter(), return -EINVAL if the sending fails.

[PATCH] HID: lenovo: Unbreak USB/BT keyboards on non-ACPI platforms

by Janne Grunau via B4 Relay

From: Janne Grunau <j(a)jannau.net> Commit 84c9d2a968c8 ("HID: lenovo: Support for ThinkPad-X12-TAB-1/2 Kbd Fn keys") added a dependency on ACPI_PLATFORM_PROFILE to cycle through power profiles. This breaks USB and Bluetooth keyboards on non-ACPI platforms since platform_profile_init() fails. See the warning below for the visible symptom but cause is the dependency on the platform_profile module.

[PATCH] RDMA/irdma: puda: Clear entries after allocation to ensure clean state

by Wentao Liang

The irdma_puda_send() calls the irdma_puda_get_next_send_wqe() to get entries, but does not clear the entries after the function call. This could lead to wqe data inconsistency. A proper implementation can be found in irdma_uk_send(). Add the irdma_clr_wqes() after irdma_puda_get_next_send_wqe(). Add the headfile of the irdma_clr_wqes().
