    leds: renesas: fix error handling · 4a5a4184
    Arnd Bergmann authored
    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]
