3.19.8-ckt7 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Vincent Pelletier <[email protected]> commit 1ae5ddb6f8837558928a1a694c7b8af7f09fdd21 upstream. GPIOF_IN flag was lost in: Commit 633a21d80b4a("input: gpio_keys_polled: Add support for GPIO descriptors"). Without this flag, legacy code path (for non-descriptor GPIO declarations) would configure GPIO as output (0 meaning GPIOF_DIR_OUT | GPIOF_INIT_LOW).
