Subject[PATCH] mtd: nand: lpc32xx_mlc: Fix an error handling path in lpc32xx_nand_probe()
Date
If 'clk_prepare_enable()' fails, we must 'put' the corresponding clock.

Fixes: 4d26f012ab59 ("mtd: nand: lpc32xx_mlc: Handle return value of clk_prepare_enable.")

Labels in the error handling path could be renamed, but it does not worth
the effort, IMHO.
