[PATCH 0/7] mfd: Drop IRQF_EARLY_RESUME flag

[PATCH 0/7] mfd: Drop IRQF_EARLY_RESUME flag

[Grygorii Strashko]

The IRQF_EARLY_RESUME flag is not required for nested irqs anymore,
since commit 3c646f2c6aa9 ("genirq: Don't suspend nested_thread irqs
over system suspend") was merged.
Hence, this flag can be dropped for MFD cell's devices where MFD interrupt
controller defines nested IRQs as nested threaded IRQs.

[PATCH 1/7] extcon: palmas: Drop IRQF_EARLY_RESUME flag

[Grygorii Strashko]

Palams extcon IRQs are nested threaded and wired to the Palmas
inerrupt controller. So, this flag is not required for nested irqs
anymore, since commit 3c646f2c6aa9 ("genirq: Don't suspend
nested_thread irqs over system suspend") was merged.

Applied to the togreg branch of iio.git - initially pushed out as
testing for the autobuilders to play with it.
