In the Linux kernel, the following vulnerability has been resolved:

clk: mediatek: fix ofiomap memory leak

Smatch reports: drivers/clk/mediatek/clk-mtk.c:583 mtkclksimpleprobe() warn: 'base' from ofiomap() not released on lines: 496.

This problem was also found in linux-next. In mtkclksimpleprobe(), base is not released when handling errors if clkdata is not existed, which may cause a leak. So freebase should be added here to release base.
