[PATCH 0/5] gpio: fix IRQ handling and probe error paths in five drivers

[shao.mingyin]

Five independent fixes in drivers/gpio/.  One stops an IRQ mask write
from enabling every other line in the bank, two stop probe from
swallowing -EPROBE_DEFER so that the controller is retried once its
parent interrupt controller is ready, one makes the 104-IDI-48 IRQ
status register accessible again, and one keeps a missing device
property from being mistaken for a multi-gigabyte allocation.

The patches touch five separate drivers and have no shared dependency;
they are ordered by severity and can be reviewed, applied and taken
individually:

  1/5 gpio: rcar: don't clobber INTMSK when disabling a single line
  2/5 gpio: aspeed-sgpio: propagate IRQ setup error in probe
  3/5 gpio: 104-idi-48: fix max_register blocking the IRQ register
  4/5 gpio: brcmstb: don't turn platform_get_irq errors into -ENOENT
  5/5 gpio: line-mux: fix unsigned truncation of property count error

1/5 is a one-line read-modify-write in the R-Car mask path; 2/5 and 4/5
return the original platform_get_irq() error, including -EPROBE_DEFER;
3/5 raises max_register by one to cover the IRQ status/enable register;
5/5 makes the property count signed and rejects non-positive values.

All five are single-file changes under drivers/gpio/ and pass git apply
and checkpatch.  All go through the GPIO tree.
