Subject: [PATCH v3 1/3] input: gpio-keys: Remove extra call to input_sync

The input_sync() function is already called after the loop in
gpio_keys_report_state(), so it does not need to be called after each
iteration within gpio_keys_gpio_report_event().

Signed-off-by: Paul Cercueil <paul@...pouillou.net>

Notes:
    v2: Keep the input_sync() within gpio_keys_report_state() so that it's
        not called at every iteration of the loop.
    
    v3: No change
