Subject: ARM: pxa: remove irq_to_gpio from ezx-pcap driver
From: Arnd Bergmann <[email protected]>
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]
