Subject: aoe: fix sysfs_create_file warnings
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4ca5224f3ea4779054d96e885ca9b3980801ce13;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

aoe: fix sysfs_create_file warnings

Moved the attributes into a group, making the compiler be quiet about
ignoring the return value of the file create calls.  This also also
fixed a bug when removing the files, which were not symlinks.
