Subject: [PATCH] clk: socfpga: arria10: Fix memory leak of socfpga_clk on error return

From: Colin Ian King <colin.king@...onical.com>

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")
