Don't allow sleep when getting the gpio value in the irq-handler. On my rk3288 board this results in might_sleep warnings when receiving data like: BUG: sleeping function called from invalid context at drivers/gpio/gpiolib.c:1531 in_atomic(): 1, irqs_disabled(): 128, pid: 0, name: swapper/0 CPU: 0 PID: 0 Comm: swapper/0 Tainted: P 4.1.0-rc5+ #2011 Hardware name: Rockchip (Device Tree) [<c00189a0>] (unwind_backtrace) from [<c0013b04>] (show_stack+0x20/0x24) [<c0013b04>] (show_stack) from [<c0757970>] (dump_stack+0x8c/0xbc) [<c0757970>] (dump_stack) from [<c0053188>] (___might_sleep+0x238/0x284) [<c0053188>] (___might_sleep) from [<c0053264>] (__might_sleep+0x90/0xa4) [<c0053264>] (__might_sleep) from [<c02ff4ac>] (gpiod_get_raw_value_cansleep+0x28/0x44) [<c02ff4ac>] (gpiod_get_raw_value_cansleep) from [<bf0363c4>] (gpio_ir_recv_irq+0x24/0x6c [gpio_ir_recv]) [<bf0363c4>] (gpio_ir_recv_irq [gpio_ir_recv]) from [<c008a78c>] (handle_irq_event_percpu+0x164/0x550) [<c008a78c>] (handle_irq_event_percpu) from [<c008abc4>] (handle_irq_event+0x4c/0x6c) [<c008abc4>] (handle_irq_event) from [<c008df88>] (handle_edge_irq+0x128/0x150) [<c008df88>] (handle_edge_irq) from [<c0089edc>] (generic_handle_irq+0x30/0x40) [<c0089edc>] (generic_handle_irq) from [<c02fc4cc>] (rockchip_irq_demux+0x158/0x210) [<c02fc4cc>] (rockchip_irq_demux) from [<c0089edc>] (generic_handle_irq+0x30/0x40) [<c0089edc>] (generic_handle_irq) from [<c008a058>] (__handle_domain_irq+0x98/0xc0) [<c008a058>] (__handle_domain_irq) from [<c00094a4>] (gic_handle_irq+0x4c/0x70) [<c00094a4>] (gic_handle_irq) from [<c0014684>] (__irq_svc+0x44/0x5c) Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> |
