Subject: sh: Ignore R_SH_NONE module relocations.
X-Git-Tag: firefly_0821_release~7613^2~1310^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=78207ffd0e00d39238f0a8a455a31a12659b30b3;p=firefly-linux-kernel-4.4.55.git

sh: Ignore R_SH_NONE module relocations.

Some modules may end up with R_SH_NONE relocs with the right combination
of compiler/kernel config (specifically dwarf unwinder), so simply trap
and ignore them instead of letting them get down to the error path.
