Subject: spi: Use kcalloc() in spi_register_board_info()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f9bdb7fdd2cac17bdc9c344b6036e6939fa087cd;p=linux.git

spi: Use kcalloc() in spi_register_board_info()

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.
