Subject: [PATCH 01/17] spi: Use kcalloc() in spi_register_board_info()
Date: Fri, 13 Jan 2017 18:07:36 +0100 [thread overview]
Message-ID: <26b9015b-7ba2-3e26-5075-9a78f3884392@users.sourceforge.net> (raw)
In-Reply-To: <1413e173-dbac-7a6e-09cb-2287300a335e@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 13 Jan 2017 12:28:04 +0100
A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus reuse the corresponding function "kcalloc".
This issue was detected by using the Coccinelle software.
