It should be changed to:

Otherwise, irq control bit is mess.

mfd: Delay to mask tsc irq in max8925

There're two IRQ pins output from MAX8925. One is PMIC interrupt, the other
is TSC interrupt. But they're sharing one irq chip.

After initializing MAX8925 interrupts, unexpected TSC interrupt may occur and
it can't be cleared if touch driver isn't loaded.

Now move the operation of masking TSC interrupt behind requesting PMIC
interrupt. If touch driver isn't loaded, this interrupt is always masked.

The Kconfig currently controlling compilation of this code is:

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

We delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

mfd: Kill off set_irq_flags usage

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.
