From: Hosung Kim Date: Thu, 2 Aug 2018 02:18:37 +0000 (+0900) Subject: [ERD][NEUS7920-76] [COMMON] lib: dss: refactor dbg_snapshot_irq logging X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=32feb52d61da3f3496a0c9866bb0662997eeaf17;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [ERD][NEUS7920-76] [COMMON] lib: dss: refactor dbg_snapshot_irq logging This commit refactors logging of dbg_snapshot_irq as following. 1. Remove dbg_snapshot_irq_exit logging (actually it is merged to dbg_snapshot_irq like measuring latency) 2. Adding logging actually called function in smp_call_function to dbg_snapshot_irq. its flag is DSS_FLAG_SMP_CALL_FN. 3. Replace logging from irqaction structure to irq_desc structure. irq_desc includes irqaction and it has more informations. And we are too hard to see it in ramdump.
