KASAN throws the following warning in rt1011.c: [ 170.777603] BUG: KASAN: stack-out-of-bounds in _find_next_bit.constprop.0+0x3e/0xf0
find_next_bit() relies on unsigned long pointer arguments, but this driver uses a type cast that generates the KASAN warning. Replace find_next_bit() and find_last_bit() with __ffs() and __fls() to pass the value and avoid casting pointers to make the warning go away.

Thanks!
[1/1] ASoC: rt1011: fix KASAN out-of-bounds bug in find_next_bit() commit: ee8a41cd30a99b39bd5d46280cc778e275cd2390
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
