[PATCH] drivers: hid: Remove dead storage

From: Tapasweni Pathak
Date: Sat Sep 29 2018 - 12:06:58 EST


Remove storing of return value of ntrig_version_string function
to ret as it is a dead storage and not used afterwards.

Found using Facebook's Infer. Build tested it.

There is another option to instead check for non zero return
value for ntrig_version_string() as a successful completion
of the function. ntrig_version_string() returns the length
of output printed by sprintf() after converting the raw firmware
code into a 5 comma separated numbers.
