From 02269ab10f1130d35dc35db72ab026d16ba31abf Mon Sep 17 00:00:00 2001 From: Dmitry Artamonow Date: Thu, 12 Apr 2012 15:33:34 +0400 Subject: mfd: Fix asic3_gpio_to_irq Assumption that irq numbers of asic3 gpios start at IRQ_BOARD_START is certainly wrong - driver may as well use any other base for its irqs (consider for example the imaginary case of two ASIC3 chips onboard) Furthermore, some platforms even don't have IRQ_BOARD_START defined, so driver will fail to build on them: ------------------------------------------------------- drivers/mfd/asic3.c: In function 'asic3_gpio_to_irq': drivers/mfd/asic3.c:530: error: 'IRQ_BOARD_START' undeclared (first use in this function) drivers/mfd/asic3.c:530: error: (Each undeclared identifier is reported only once drivers/mfd/asic3.c:530: error: for each function it appears in.) ------------------------------------------------------- Fix it by using irq_base from driver data.
