extcon: palmas: Drop stray IRQF_EARLY_RESUME flag
Palmas extcon IRQs are nested threaded and wired to the Palmas interrupt controller. So, this flag is not required for nested IRQs anymore, since commit 3c646f2c6aa9 ("genirq: Don't suspend nested_thread irqs over system suspend") was merged. However, the fix in commit ae64e42cc2b3 ("extcon: palmas: Drop IRQF_EARLY_RESUME flag") missed a stray flag causing the following crash on resume on BeagleBoard-X15 platform: [ 53.670141] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [..] [ 53.670141] [<c04ae734>] (omap_set_gpio_triggering) from [<c04aeb94>] (omap_gpio_unmask_irq+0xc0/0xc4) [ 53.670141] [<c04aeb94>] (omap_gpio_unmask_irq) from [<c01a0b88>] (irq_enable+0x30/0x44) [ 53.670141] [<c01a0b88>] (irq_enable) from [<c019ebd8>] (__enable_irq+0x54/0x78) [ 53.670141] [<c019ebd8>] (__enable_irq) from [<c01a4e60>] (resume_irqs+0xe8/0x100) [ 53.670141] [<c01a4e60>] (resume_irqs) from [<c0514840>] (syscore_resume+0x94/0x298) [ 53.670141] [<c0514840>] (syscore_resume) from [<c01981cc>] (suspend_devices_and_enter+0x790/0x9e4) [ 53.670141] [<c01981cc>] (suspend_devices_and_enter) from [<c0198a60>] (pm_suspend+0x640/0x75c) [ 53.670141] [<c0198a60>] (pm_suspend) from [<c0196bec>] (state_store+0x64/0xb8) [ 53.670141] [<c0196bec>] (state_store) from [<c0307944>] (kernfs_fop_write+0xc0/0x1bc) [ 53.670141] [<c0307944>] (kernfs_fop_write) from [<c028acb0>] (__vfs_write+0x1c/0xd8) [ 53.670141] [<c028acb0>] (__vfs_write) from [<c028bba0>] (vfs_write+0x90/0x16c) [ 53.670141] [<c028bba0>] (vfs_write) from [<c028c8c0>] (SyS_write+0x44/0x9c) [ 53.670141] [<c028c8c0>] (SyS_write) from [<c0107840>] (ret_fast_syscall+0x0/0x1c) [..] Fixes: ae64e42cc2b3 ("extcon: palmas: Drop IRQF_EARLY_RESUME flag") Cc: Grygorii Strashko <grygorii.strashko@ti.com> Cc: MyungJoo Ham <myungjoo.ham@samsung.com> Cc: Chanwoo Choi <cw00.choi@samsung.com> Cc: Tony Lindgren <tony@atomide.com> Cc: Lee Jones <lee.jones@linaro.org> Cc: Roger Quadros <rogerq@ti.com> Reviewed-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Acked-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
