Subject: [PATCH 2/2] Input: matrix_keypad: Improve a size determination in matrix_keypad_probe()
Date: Sat, 27 Jan 2018 13:54:23 +0100	[thread overview]
Message-ID: <8098317f-46bb-fefb-936c-eb82605c565c@users.sourceforge.net> (raw)
In-Reply-To: <106bffd0-28ed-7c33-1f32-ae84b40f52c7@users.sourceforge.net>

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.
