Subject: [PATCH] Input: imx_sc_key - Fix memory corruption on unload

This is supposed to be "priv" but we accidentally pass "&priv" which is
an address in the stack and so it will lead to memory corruption when
the imx_sc_key_action() function is called.  Remove the &.

Fixes: 768062fd1284 ("Input: imx_sc_key - use devm_add_action_or_reset() to handle all cleanups")
