[ Upstream commit bfbea9e5667cfa9552c3d88f023386f017f6c308 ]

In cases where kcalloc() fails for the 'clk_data->clks' allocation, the
code path does not handle the failure gracefully, potentially leading
to a memory leak. This fix ensures proper cleanup by freeing the
allocated memory for 'clk_data' before returning.

[ Upstream commit 2fbabea626b6467eb4e6c4cb7a16523da12e43b4 ]

In cases where mapping of mpmu/apmu/apbc registers fails, the code path
does not handle the failure gracefully, potentially leading to a memory
leak. This fix ensures proper cleanup by freeing the allocated memory
for 'pxa_unit' before returning.
