mtd: mxc_nand: fix unbalanced clk_disable() in error path
If nand_scan_ident() or nand_scan_tail() fails, the NAND chip may have been deselected and the clock already disabled. Thus, check 'clk_act' in the error path to decide whether the clock still needs to be disabled. This fixes a: |WARNING: at drivers/clk/clk.c:472 __clk_disable+0x3c/0x78() Signed-off-by: Lothar Waßmann <LW@KARO-electronics.de> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
