Hi all,

After merging the kunit-next tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

lib/bitfield_kunit.c: In function 'test_bitfields_compile':
lib/bitfield_kunit.c:136:21: warning: unsigned conversion from 'int' to 'u16' {aka 'short unsigned int'} changes value from '393216' to '0' [-Woverflow]
136 | u16_encode_bits(0, 0x60000);
| ^~~~~~~
At top level:
lib/bitfield_kunit.c:129:20: warning: 'test_bitfields_compile' defined but not used [-Wunused-function]
129 | static void __init test_bitfields_compile(struct kunit *context)
| ^~~~~~~~~~~~~~~~~~~~~~

Introduced by commit

I saw the problem, I will send the patch.


Please send the fix in as soon as possible. I will go ahead and send the
pull request and will apply the fix in rc2.

thanks,
