Subject: [PATCH] regmap-irq: Drop map from handle_mask_sync() parameters
Remove the map parameter from the struct regmap_irq_chip callback
handle_mask_sync() because it can be passed via the irq_drv_data
parameter instead. The gpio-104-dio-48e driver is the only consumer of
this callback and is thus updated accordingly.
