3.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit 59ee93a528b94ef4e81a08db252b0326feff171f upstream.
The irq_to_gpio function was removed from the pxa platform in linux-3.2, and this driver has been broken since.
There is actually no in-tree user of this driver that adds this platform device, but the driver can and does get enabled on some platforms.
Without this patch, building ezx_defconfig results in:
drivers/mfd/ezx-pcap.c: In function 'pcap_isr_work': drivers/mfd/ezx-pcap.c:205:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration]
