[PATCH] module: stats: fix invalid_mod_bytes typo

[PATCH] module: stats: fix invalid_mod_bytes typo

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

This was caught by randconfig builds but does not show up in
build testing without CONFIG_MODULE_DECOMPRESS:

kernel/module/stats.c: In function 'mod_stat_bump_invalid':
kernel/module/stats.c:229:42: error: 'invalid_mod_byte' undeclared (first use in this function); did you mean 'invalid_mod_bytes'?
  229 |   atomic_long_add(info->compressed_len, &invalid_mod_byte);
      |                                          ^~~~~~~~~~~~~~~~
      |                                          invalid_mod_bytes

Fixes: 0d4ab68ce983 ("module: add debug stats to help identify memory pressure")

This was probably already reported, sending the fix just in case everyone
else else missed it so far.

Oh it was a decompression ifdef, that's why I didn't catch it! But also
I guess 0-day isn't running tests with it enabled either!

Thanks! Applied and pushed!
