Subject: firmware-gsmi: Delete an unnecessary check before the function call "dma_pool_destroy"
X-Git-Tag: v4.9-rc1~166^2~2^2~11
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d520dd1f348dcaafcb8ce804b2a5ebb1be004719;p=karo-tx-linux.git

firmware-gsmi: Delete an unnecessary check before the function call "dma_pool_destroy"

The dma_pool_destroy() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
