Subject: [PATCH] sound/oss/btaudio.c: ioremap balanced with iounmap
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b9d85b08c689dbf54b9943a02f73cb54c2b0fccf;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] sound/oss/btaudio.c: ioremap balanced with iounmap

ioremap must be balanced by an iounmap and failing to do so can result
in a memory leak.
