Subject: [PATCH] mtd: rawnand: meson: Fix a resource leak in init
Git-commit: ad8566d3555c4731e6b48823b92d3929b0394c14
Patch-mainline: v5.11-rc1
References: git-fixes

Call clk_disable_unprepare(nfc->phase_rx) if the clk_set_rate() function
fails to avoid a resource leak.

Fixes: 8fae856c5350 ("mtd: rawnand: meson: add support for Amlogic NAND flash controller")
