Chen-Yu Tsai 10098709b4 pinctrl: sunxi: Correct number of IRQ banks on H6 main pin controller 
The H6 main pin controller has four banks of interrupt-triggering pins.
The driver as originally submitted only specified three, but had pin
descriptions referencing a fourth bank. This results in a out-of-bounds
access into .irq_array of struct sunxi_pinctrl. This however did not
result in a crash until v4.20, with commit a66d972465 ("devres: Align
data[] to ARCH_KMALLOC_MINALIGN"), which changed the alignment of memory
region returned by devm_kcalloc(). The increase likely moved the
out-of-bounds access into the next, unmapped page.

With KASAN on, the bug is quite clear:

Correct the number of IRQ banks so there are no more mismatches.
