From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently the check for the error return code -ERESTARTSYS is dead code
and never executed because a previous check for ret < 0 is catching this
and returning -ETIMEDOUT instead. Fix this by checking for -ERESTARTSYS
before the more generic negative error code.
Addresses-Coverity: ("Logically dead code")
Fixes: 4b2c53d93a4b ("SFH:Transport Driver to add support of AMD Sensor Fusion Hub (SFH)")
