[PATCH] ASoC: adau1373: adau1373_hw_params: Silence overflow warning

[Tim Gardner]

ADAU1373_BCLKDIV_SOURCE is defined as BIT(5) which uses UL constants. On
amd64 the result of the ones complement operator is then truncated to
unsigned int according to the prototype of snd_soc_update_bits(). I think
gcc is correctly warning that the upper 32 bits are lost.

That seems way more complicated then need be. It also uses 2 bits in the
mask whereas the original code only used 1, e.g., bit 5. Is that correct ?

How about just open coding the macro thusly:

#define ADAU1373_BCLKDIV_SOURCE (1<<5) /*BIT(5)*/

The BCLKDIV has three fields. The bitclock divider (bit 0-1), the samplerate
(bit 2-4) and the source select (bit 5). Here we want to update the bitclock
divider field and the samplerate field. When I wrote the code I was lazy and
used ~ADAU1373_BCLKDIV_SOURCE as the mask, which for this register is
functional equivalent to ADAU1373_BCLKDIV_SR_MASK | ADAU1373_BCLKDIV_BCLK_MASK.

But now there is a inconsistency where we sometimes use (1<<x) and sometimes
BIT(x). I prefer my solution.

[PATCH linux-next v2] ASoC: adau1373: adau1373_hw_params: Silence overflow warning

ADAU1373_BCLKDIV_SOURCE is defined as BIT(5) which uses UL constants. On
amd64 the result of the ones complement operator is then truncated to

gcc is correctly warning that the upper 32 bits are lost.

Add 2 more BCLKDIV mask macros as explained by Lars:

I'm just going by the default output of scripts/get_maintainer.pl. Are
there better options to filter the roles ? In this case I received a
review from a supporter (Lars), and the patch is being committed by
yet another supporter (yourself). Would you have noticed this patch
had I restricted the Cc list to just maintainers and lists ?

I specifically mean don't include the lists in the body of the mail - it
means they either litter the git log or need to be manually deleted.  If
you're just using unfiltered get_maintainer output then I'd suggest that
you generate the CCs in your scripts when sending rather than putting
them in the changelog.
