Depending on the architecture __ffs() returns either an 'unsigned long'
or 'unsigned int' result. Compile-testing this driver on targets that
use the latter produces a warning:

sound/soc/intel/catpt/dsp.c: In function 'catpt_dsp_set_srampge':
sound/soc/intel/catpt/dsp.c:181:44: error: format '%ld' expects argument of type 'long int', but argument 4 has type 'u32' {aka 'unsigned int'} [-Werror=format=]
  181 |                         dev_dbg(cdev->dev, "sanitize block %ld: off 0x%08x\n",
      |                                            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Change the type of the local variable to match the format string and
avoid the warning on any architecture.

Applied to

Thanks!

[1/1] ASoC: Intel: catpt: avoid type mismatch in dev_dbg() format
      commit: 95b2536137eeb66f20947e0fb0d0c100c8d6a140

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
