Subject: sh: unwinder: Restore put_unaligned() for an unaligned destination.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bf43a160ff2d67a21b076286bab6f5e2c993bd0a;p=linux-beck.git

sh: unwinder: Restore put_unaligned() for an unaligned destination.

The destination address might be unaligned, so set it with
put_unaligned() for safety. This restores the previous behaviour, albeit
through the proper API.
