From ce93bedb5ed2b16c08c6df4c797865f9ead600a3 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Sat, 22 Oct 2016 14:15:22 -0200 Subject: mtd: nand: gpmi: disable the clocks on errors We should disable the previously enabled GPMI clocks in the error paths. Also, when gpmi_enable_clk() fails simply return the error code immediately rather than jumping to to the 'err_out' label.
