The clock needed by the I2S driver is associated with the I2S device name in the standard fashion. Hence, use clk_get(dev) instead of clk_get_sys(clk_name). Signed-off-by:

The I2S controller needs a clock to respond to register writes. Without this, register writes will at worst hang the CPU. In practice, I've only observed writes being dropped. Luckily, the dropped register writes historically had no effect: TEGRA_I2S_TIMING: The value we wrote was the reset default. TEGRA_I2S_FIFO_SCR: The default was for the FIFOs to request more data when one slot was empty. The requested value was for the FIFOs to request when four slots were empty. The DMA controller in the mainline kernel is configured to burst a single entry at a time into the FIFO, hence there was no issue. The only negative effect was on bus efficiency losses due to an increased number of arbitration attempts. However, in various non-upstream changes, the DMA controller now bursts four entries at a time into the FIFO. If there is only space for one entry, the data is simply dropped. In practice, this resulted in 3/4 of samples being dropped, and playback at 4x the expected rate and pitch. By fixing the clocking issue, this is solved. Signed-off-by:

The Blackfin DMA controller can report one frame beyond the end of the buffer in the wraparound case but ALSA requires that the pointer always be in the buffer. Do the wraparound to handle this. A similar bug is likely to apply to the other Blackfin PCM drivers but the code is less obvious to inspection and I don't have a user to test. Reported-by:

The base hardware revision of the Maxim 98095 part is 0x40; the code which outputs the revision of the hardware has been updated to properly use uppercase alphabetic values for the revision numbers. Also, the use of a constant for the length 'max98095_dai' has been replaced with ARRAY_SIZE(). Signed-off-by:

Previously we were using the DAPM context rather than a widget as the argument for update_bits() so we didn't need to care that our list walk of widgets left us one beyond the end of the list. Now we're using them for the register update we need to make sure we're pointing at an actual widget not the list_head. Fix originally suggested by Liam on IM. Signed-off-by:
