[PATCH 0/5] mfd: Fix an out-of-bounds IRQ map and error-path bugs

[shao.mingyin]

Five independent fixes in the MFD core address an out-of-bounds IRQ-map
lookup, an uninitialized interrupt-mask write, an IRQ leak on a failed
probe, a missing IRQ-wake teardown on removal, and two unchecked
firmware CRC reads.  Each patch touches a different driver; they are
grouped only because they go through the same MFD tree.  Every patch is
independent and can be applied and reviewed on its own, and taking a
subset is fine.

The series is ordered by severity:

  1/5 mfd: tps65219: Fix out-of-bounds access in tps65214 IRQ map
  2/5 mfd: twl6030-irq: Don't write garbage to interrupt mask on read failure
  3/5 mfd: arizona: Free info IRQs on probe failure
  4/5 mfd: da9052: Disable IRQ wake on device removal
  5/5 mfd: gateworks-gsc: Check firmware CRC reads for errors

1/5 adds the missing reserved-bit placeholder so that a power-button
interrupt no longer indexes past tps65214_sub_irq_offsets[].  2/5
returns the I2C read error instead of writing uninitialized stack data
to the PMIC interrupt mask.  3/5 frees the three informational IRQs
before arizona_irq_exit() tears down their domain.  4/5 tracks whether
enable_irq_wake() succeeded and disables it on the probe failure and
removal paths.  5/5 checks the two GSC_FW_CRC reads and fails the probe
instead of printing a stale CRC.

No dependencies; all five apply directly on next-20261030.
