Subject: rfkill: do not fsync(3) /dev/rfkill file descriptor
X-Git-Tag: v2.31-rc1~78
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b120966812809c816a184f21bf10c65ed837bf49;p=thirdparty%2Futil-linux.git

rfkill: do not fsync(3) /dev/rfkill file descriptor

Attempt to fsync() this device returns EINVAL, causing the rfkill always to
return EXIT_FAILURE when either block or unblock is requested.  Simply
closing the file descriptor will fix the issue.
