Subject: [PATCH 2/2] Input: sur40: Improve a size determination in sur40_probe()
Date: Sat, 20 Jan 2018 22:30:08 +0100	[thread overview]
Message-ID: <11e0b313-f8c2-93ec-0324-24b30053a586@users.sourceforge.net> (raw)
In-Reply-To: <a7e25da3-587a-f0e8-d574-8066b340d9a6@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.
