leds: renesas: fix error handling
bfe4c041 "leds: convert Renesas TPU LED driver to devm_kzalloc() and cleanup error exit path" introduced a possible case in which r_tpu_probe calls iounmap on a wild pointer. This changes the one case that was missed in the same way as the other error paths. Without this patch, building kota2_defconfig results in: drivers/leds/leds-renesas-tpu.c: In function 'r_tpu_probe': drivers/leds/leds-renesas-tpu.c:246:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] drivers/leds/leds-renesas-tpu.c:308:17: warning: 'p' may be used uninitialized in this function [-Wuninitialized] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Magnus Damm <damm@opensource.se> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>
