[PATCH AUTOSEL 6.3 01/30] Input: soc_button_array - add invalid acpi_index DMI quirk handling
From: Hans de Goede hdegoede@redhat.com
[ Upstream commit 20a99a291d564a559cc2fd013b4824a3bb3f1db7 ]
Some devices have a wrong entry in their button array which points to a GPIO which is required in another driver, so soc_button_array must not claim it.
A specific example of this is the Lenovo Yoga Book X90F / X90L, where the PNP0C40 home button entry points to a GPIO which is not a home button and which is required by the lenovo-yogabook driver.
Add a DMI quirk table which can specify an ACPI GPIO resource index which should be skipped; and add an entry for the Lenovo Yoga Book X90F / X90L to this new DMI quirk table.

regmap-sdw does not support multi register writes, so there is no point in setting this flag. This also leads to incorrect programming of WSA codecs with regmap_multi_reg_write() call.
This invalid configuration should have been rejected by regmap-sdw.

[ Upstream commit fa58cc888d67e640e354d8b3ceef877ea167b0cf ]
When a direct I/O write is performed, iomap_dio_rw() invalidates the part of the page cache which the write is going to before carrying out the write. In the odd case, the direct I/O write will be reading from the same page it is writing to. gfs2 carries out writes with page faults disabled, so it should have been obvious that this page invalidation can cause iomap_dio_rw() to never make any progress. Currently, gfs2 will end up in an endless retry loop in gfs2_file_direct_write() instead, though.
Break this endless loop by limiting the number of retries and falling back to buffered I/O after that.
Also simplify should_fault_in_pages() sightly and add a comment to make the above case easier to understand.

There's an issue on SAI synchronous mode that TX/RX side can't get BCLK from RX/TX it sync with if BYP bit is asserted. It's a workaround to fix it that enable SION of IOMUX pad control and assert BCI.
For example if TX sync with RX which means both TX and RX are using clk form RX and BYP=1. TX can get BCLK only if the following two conditions are valid: 1. SION of RX BCLK IOMUX pad is set to 1 2. BCI of TX is set to 1

[ Upstream commit 1acfc6e753ed978b36d722f54e57fe4d1e8a6ffa ]
With IC_INTR_RX_FULL slave interrupt handler reads data in a loop until RX FIFO is empty. When testing with the slave-eeprom, each transaction has 2 bytes for address/index and 1 byte for value, the address byte can be written as data byte due to dropping STOP condition.
In the test below, the master continuously writes to the slave, first 2 bytes are index, 3rd byte is value and follow by a STOP condition.
i2c_write: i2c-3 #0 a=04b f=0000 l=3 [00-D1-D1] i2c_write: i2c-3 #0 a=04b f=0000 l=3 [00-D2-D2] i2c_write: i2c-3 #0 a=04b f=0000 l=3 [00-D3-D3]
Upon receiving STOP condition slave eeprom would reset `idx_write_cnt` so next 2 bytes can be treated as buffer index for upcoming transaction. Supposedly the slave eeprom buffer would be written as
EEPROM[0x00D1] = 0xD1 EEPROM[0x00D2] = 0xD2 EEPROM[0x00D3] = 0xD3
When CPU load is high the slave irq handler may not read fast enough, the interrupt status can be seen as 0x204 with both DW_IC_INTR_STOP_DET (0x200) and DW_IC_INTR_RX_FULL (0x4) bits. The slave device may see the transactions below.
0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4 0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4 0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4 0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1794 : INTR_STAT=0x204 0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x1790 : INTR_STAT=0x200 0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4 0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4 0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4
After `D1` is received, read loop continues to read `00` which is the first bype of next index. Since STOP condition is ignored by the loop, eeprom buffer index increased to `D2` and `00` is written as value.
So the slave eeprom buffer becomes
EEPROM[0x00D1] = 0xD1 EEPROM[0x00D2] = 0x00 EEPROM[0x00D3] = 0xD3
The fix is to use `FIRST_DATA_BYTE` (bit 11) in `IC_DATA_CMD` to split the transactions. The first index byte in this case would have bit 11 set. Check this indication to inject I2C_SLAVE_WRITE_REQUESTED event which will reset `idx_write_cnt` in slave eeprom.

Fix a wrong error return by dropping an error return.
When vidi driver is remvoed, if ctx->raw_edid isn't same as fake_edid_info then only what we have to is to free ctx->raw_edid so that driver removing can work correctly - it's not an error case.

ext4_xattr_block_set() relies on its caller to call dquot_initialize() on the inode. To assure that this has happened there are WARN_ON checks. Unfortunately, this is subject to false positives if there is an antagonist thread which is flipping the file system at high rates between r/o and rw. So only do the check if EXT4_XATTR_DEBUG is enabled.
