commit ebb6ad73 upstream. VMID Control 0 BIT[2:1] is VMID Divider Enable and Select 00 = VMID disabled (for OFF mode) 01 = 2 x 50kΩ divider (for normal operation) 10 = 2 x 250kΩ divider (for low power standby) 11 = 2 x 5kΩ divider (for fast start-up) So WM8903_VMID_RES_250K should be 2 << 1, which is 4.

commit 0574eab3 upstream. I tried to fix this before and submitted a working patch, but after some discussion we came up with what seemed to be a nicer solution, resulting in commit 3d4cf65e ("ASoC: omap: fix up SND_OMAP_SOC_OMAP_ABE_TWL6040 dependency"). Unfortunately, that version was incomplete, and we still get this build error: drivers/clk/clk-palmas.c:46:16: error: field 'hw' has incomplete type drivers/clk/clk-palmas.c: In function 'to_palmas_clks_info': drivers/clk/clk-palmas.c:54:74: warning: initialization from incompatible pointer type [-Winc This happens only in randconfig builds that turn on MFD_PALMAS on a platform other than OMAP2+ when COMPILE_TEST is set but COMMON_CLK is not. The new approach is only 'select COMMON_CLK_PALMAS' if we know that we are on an OMAP5 platform and MFD_PALMAS is already set. This patch has survived thousands of randconfig builds and I don't see a remaining hole in the logic.

commit a7310c49 upstream. Compile-tests show a warning for the newly added SND_SOC_STORM symbol: warning: (SND_SOC_STORM) selects SND_SOC_LPASS_CPU which has unmet direct dependencies (SOUND && !M68K && !UML && SND && SND_SOC && SND_SOC_QCOM) The problem is that it can be selected for COMPILE_TEST on non-QCOM builds, but the symbols it selects have a dependency. Dropping the dependencies makes it work without warnings and no other side-effects, because these are not user-visible.

commit 77a3c6fd upstream. Commit f61bf13b ("[media] vb2: add allow_zero_bytesused flag to the vb2_queue struct") added a WARN_ONCE to catch usage of a deprecated API using a zero value for v4l2_buffer.bytesused. However, the condition is checked incorrectly, as the v4L2_buffer bytesused field is supposed to be ignored for multiplanar buffers. This results in spurious warnings when using the multiplanar API. Fix it by checking v4l2_buffer.bytesused for uniplanar buffers and v4l2_plane.bytesused for multiplanar buffers.

commit bdc10d57 upstream. Current description for proximity measurement is ambiguous. While the first part says that proximity is measured by observing reflectivity, the second part incorrectly infers that reported values should behave like a distance. This is because of AS3935 lightning sensor which uses the proximity API, while not being a true proximity sensor. Note this is marked for stable as it accompanies a fix in ABI usage to the sx9500 driver which would otherwise appear to be correct.

commit e766f338 upstream. Newly introduced quirks infrastructure doesn't work for the devices behind MUXes because MUX's master_xfer() calls parent's master_xfer() directly without checking the quirks. Instead of duplicating check code in MUX just call __i2c_transfer() instead. This has a side effect on tracing (messages will appear on both MUX bus and parent bus), but maybe that's not bad at the end.

commit 93563a6a upstream. For TX transactions, the TXCOMP bit in the Status Register is cleared when the first data is written into the Transmit Holding Register. In the lines from at91_do_twi_transfer(): at91_twi_write_data_dma(dev); at91_twi_write(dev, AT91_TWI_IER, AT91_TWI_TXCOMP); the TXCOMP interrupt may be enabled before the DMA controller has actually started to write into the THR. In such a case, the TXCOMP bit is still set into the Status Register so the interrupt is triggered immediately. The driver understands that a transaction completion has occurred but this transaction hasn't started yet. Hence the TXCOMP interrupt is no longer enabled by at91_do_twi_transfer() but instead by at91_twi_write_data_dma_callback(). Also, the TXCOMP bit in the Status Register in not a clear on read flag but a snapshot of the transmission state at the time the Status Register is read. When a NACK error is dectected by the I2C controller, the TXCOMP, NACK and TXRDY bits are set together to 1 in the SR. If enabled, the TXCOMP interrupt is triggered at the same time. Also setting the TXRDY to 1 triggers the DMA controller to write the next data into the THR. Such a write resets the TXCOMP bit to 0 in the SR. So depending on when the interrupt handler reads the SR, it may fail to detect the NACK error if it relies on the TXCOMP bit. The NACK bit and its interrupt should be used instead. For RX transactions, the TXCOMP bit in the Status Register is cleared when the START bit is set into the Control Register. However to unify the management of the TXCOMP bit when the DMA controller is used, the TXCOMP interrupt is now enabled by the DMA callbacks for both TX and RX transfers.

commit 119434f4 upstream. When entering suspend while an wakeup alarm is set, enable_set_wake should make sure that the RTC interrupt keep being enabled and the .irq_set_wake for the RTC interrupt get called. However, since the driver uses the suspend_noirq callback, the call to enable_irq_wake has been made after disabling the interrupts. While .irq_set_wake has been called properly, the interrupt remained disabled. Use the suspend callback to call enable_irq_wake early enough to ensure the RTC interrupt remains enabled.

commit 6f6a6fda upstream. If updating journal superblock fails after journal data has been flushed, the error is omitted and this will mislead the caller as a normal case. In ocfs2, the checkpoint will be treated successfully and the other node can get the lock to update. Since the sb_start is still pointing to the old log block, it will rewrite the journal data during journal recovery by the other node. Thus the new updates will be overwritten and ocfs2 corrupts. So in above case we have to return the error, and ocfs2_commit_cache will take care of the error and prevent the other node to do update first. And only after recovering journal it can do the new updates.
