Subject: [ARM] 4569/1: ep93xx_gpio_irq_type(): fix spurious enumeration offset for FGPIO handling
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8742bc92c36324ac4bac739ab413acc6630a875d;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[ARM] 4569/1: ep93xx_gpio_irq_type(): fix spurious enumeration offset for FGPIO handling

The EP93XX_GPIO_LINE_F() macro is supposed to be called with a line
number between 0 and 7, but the current code causes it to get called
with an spuriously offset number range {16..23}.
