Subject: libkmod: Add elf_get_u32() helper
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=0da79e0ab322298e2af0bd754b5970f2fd474dce;p=thirdparty%2Fkmod.git

libkmod: Add elf_get_u32() helper

Shortcut to the size.

Keep this wrapper inline even after the previous de-inlining change:
it is a tiny typed helper around elf_get_uint() that avoids repeating
the uint32_t size at call sites, while the larger helpers can still be
left to the compiler.
