Subject: [PATCH] brcmfmac: allow device tree node without 'interrupts'
|
|
property
|
|
|
|
As described in the device tree bindings for 'brcm,bcm4329-fmac'
|
|
nodes, the interrupts property is optional. So adding a check
|
|
for the presence of this property before attempting to parse
|
|
and map the interrupt. If not present or parsing fails return
|
|
and fallback to in-band sdio interrupt.
