Subject: module: fix __find_symbl() error checks
From: Akinobu Mita <[EMAIL PROTECTED]>
The patch:
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.24/2.6.24-mm1/broken-out/modules-handle-symbols-that-have-a-zero-value.patch
changes the return value of __find_symbol() so that it can handle symbols
that are zero and now it returns -errno for failure.
But some __find_symbl() error checks remain unchanged.
