Subject: genirq: Provide compat handling for chip->retrigger()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=21e2b8c62cca8f7dbec0c8c131ca1637e4a5670f;p=linux-beck.git

genirq: Provide compat handling for chip->retrigger()

Wrap the old chip function retrigger() until the migration is complete
and the old chip functions are removed.
