From: Sasha Levin

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

[ Upstream commit 657d4d1934f75a2d978c3cf2086495eaa542e7a9 ]

There is an error return path that is not kfree'ing socfpga_clk leading
to a memory leak. Fix this by adding in the missing kfree call.

Addresses-Coverity: ("Resource leak")
