The patch titled
Subject: sh: sh7757: remove nonexistent GPIO_PT[JLNQ]7_RESV to fix pinctrl registration
has been removed from the -mm tree. Its filename was
sh-sh7757-remove-nonexistent-gpio_pt7_resv-to-fix-pinctrl-registration.patch
This patch was dropped because it was merged into mainline or a subsystem tree

From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
Subject: sh: sh7757: remove nonexistent GPIO_PT[JLNQ]7_RESV to fix pinctrl registration
3810e96056ffddf6 ("sh: modify pinmux for SH7757 2nd cut") renamed
GPIO_PT[JLNQ]7 to GPIO_PT[JLNQ]7_RESV, and removed the existing users from
the pinmux_pins[] array.
However, pinmux_pins[] is initialized through PINMUX_GPIO(), using
designated array initializers, where the GPIO_* enums serve as indices.
Hence entries were not really removed, but replaced by (zero-filled)
holes. Such entries are treated as pin zero, which was registered before,
thus leading to pinctrl registration failures, as seen on sh7722:
sh-pfc pfc-sh7722: pin 0 already registered
sh-pfc pfc-sh7722: error during pin registration
sh-pfc pfc-sh7722: could not register: -22
sh-pfc: probe of pfc-sh7722 failed with error -22
Remove GPIO_PT[JLNQ]7_RESV from the enum to fix this.
