modpost: do not make find_tosym() return NULL
As mentioned in commit 397586506c3d ("modpost: Add '.ltext' and '.ltext.*' to TEXT_SECTIONS"), modpost can result in a segmentation fault due to a NULL pointer dereference in default_mismatch_handler(). find_tosym() can return the original symbol pointer instead of NULL if a better one is not found. This fixes the reported segmentation fault. Fixes: a23e7584ecf3 ("modpost: unify 'sym' and 'to' in default_mismatch_handler()") Reported-by: Nathan Chancellor <nathan@kernel.org> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
