[PATCH 0/7] pinctrl: Fix types in .pin_config_group_get() callbacks

[PATCH 0/7] pinctrl: Fix types in .pin_config_group_get() callbacks

[Geert Uytterhoeven]

	Hi all,

On 64-bit platforms, "unsigned long" is 64-bit.  However, when checking
if all "unsigned long" configuration values passed to the
.pin_config_group_get() callback are equal, several drivers use a 32-bit
temporary.  Fortunately this works, as currently all configuration
values fit in 32-bit.

This series makes the code cleaner and more future-proof by changing the
types of all temporaries to unsigned long.

I intend to queue patches 5 and 6 in renesas-pinctrl for v7.2.
Thanks for your comments!

[PATCH 1/7] pinctrl: airoha: Fix type in .pin_config_group_get() callback

[Geert Uytterhoeven]

On 64-bit platforms, "unsigned long" is 64-bit.  Hence checking if all
"unsigned long" configuration values are equal should be done using an
"unsigned long" temporary.

[PATCH 3/7] pinctrl: ingenic: Fix type in .pin_config_group_get() callback

[Geert Uytterhoeven]

On 64-bit platforms, "unsigned long" is 64-bit.  Hence checking if all
"unsigned long" configuration values are equal should be done using an
"unsigned long" temporary.

While Ingenic is a 32-bit platform, it is still better to use the
correct type, to serve as an example.

tested to show no visible difference on Ingenic X1600 based board (Letux X16) on top of v7.1-rc1.
