Subject: clk: imx: avoid memory leak
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f4419db4086e8c31821da14140e81498516a3c75;p=linux.git

clk: imx: avoid memory leak

In case imx_register_uart_clocks return early, the imx_uart_clocks
memory will be no freed. So execute kfree always to avoid memory leak.
