clk_disable() in remove method is not needed since we already have clk_disable in pxa27x_keypad_close(). Also make sure the driver uses resource_size() and helpers from include/input/matrix_keypad.h Tested-by: Mike Rapoport <mike@compulab.co.il> Acked-by: Eric Miao <eric.y.miao@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

/* pxa3xx keypad platform specific parameters
|
|
*
|
|
* NOTE:
|
|
* 1. direct_key_num indicates the number of keys in the direct keypad
|
|
* _plus_ the number of rotary-encoder sensor inputs, this can be
|
|
* left as 0 if only rotary encoders are enabled, the driver will
|
|
* automatically calculate this
|
|
*
|
|
* 2. direct_key_map is the key code map for the direct keys, if rotary
|
|
* encoder(s) are enabled, direct key 0/1(2/3) will be ignored
|
|
*
|
|
* 3. rotary can be either interpreted as a relative input event (e.g.
|
|
* REL_WHEEL/REL_HWHEEL) or specific keys (e.g. UP/DOWN/LEFT/RIGHT)
|
|
*
|
|
* 4. matrix key and direct key will use the same debounce_interval by
|
|
* default, which should be sufficient in most cases
