Subject: uio_hv_generic: add missed sysfs_remove_bin_file
X-Git-Tag: v5.15~3662^2~87
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7066c2f61ce49b131026fec68ed1c9b0d0d9a05a;p=platform%2Fkernel%2Flinux-starfive.git

uio_hv_generic: add missed sysfs_remove_bin_file

This driver calls sysfs_create_bin_file() in probe, but forgets to
call sysfs_remove_bin_file() in remove.
Add the missed call to fix it.
