Masahiro Yamada 1cd9502ee9 module: get symbol CRC back to unsigned
Commit 71810db27c ("modversions: treat symbol CRCs as 32 bit
quantities") changed the CRC fields to s32 because the __kcrctab and
__kcrctab_gpl sections contained relative references to the actual
CRC values stored in the .rodata section when CONFIG_MODULE_REL_CRCS=y.

Commit 7b4537199a ("kbuild: link symbol CRCs at final link, removing
CONFIG_MODULE_REL_CRCS") removed this complexity. Now, the __kcrctab
and __kcrctab_gpl sections directly contain the CRC values in all cases.

The genksyms tool outputs unsigned 32-bit CRC values, so u32 is preferred
over s32.

No functional changes are intended.

Regardless of this change, the CRC value is assigned to the u32 variable
'crcval' before the comparison, as seen in kernel/module/version.c:

    crcval = *crc;

It was previously mandatory (but now optional) in order to avoid sign
extension because the following line previously compared 'unsigned long'
and 's32':

    if (versions[i].crc == crcval)
            return 1;

versions[i].crc is still 'unsigned long' for backward compatibility.
