Subject: HID: 'name' and 'phys' in 'struct hid_device' can never be NULL
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dd2ed487fdd78b50549b2ca8418875c0d9f4a30e;p=linux-beck.git

HID: 'name' and 'phys' in 'struct hid_device' can never be NULL

As they are static members of fix size, there is no need to NULL-check them.
