| |
The touchscreen component driver for the da9052/3 Dialog PMICs leaks memory by not freeing the input device in the remove call.
This patch matches the existing call to input_alloc_device() in da9052_ts_probe() to a new call to input_free_device() in da9052_ts_remove()

Many thanks to Huqiu Liu who found the bug.
