[PATCH] mmc: host: fix memory leak in mmc_add_host

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



led_trigger_register_simple() allocates memory which must not be leaked
in the error-path of mmc_add_host. Move it past the only error-check in
the function.

I don't see any reason why it needs to be called before device_add.
