Subject: [PATCH] drm/panfrost: fix -Wmissing-prototypes warnings
Date: Sat, 19 Oct 2019 15:28:14 +0800 [thread overview]
Message-ID: <1571470094-39589-1-git-send-email-wang.yi59@zte.com.cn> (raw)
We get these warnings when build kernel W=1:
drivers/gpu/drm/panfrost/panfrost_perfcnt.c:35:6: warning: no previous prototype for ‘panfrost_perfcnt_clean_cache_done’ [-Wmissing-prototypes]
drivers/gpu/drm/panfrost/panfrost_perfcnt.c:40:6: warning: no previous prototype for ‘panfrost_perfcnt_sample_done’ [-Wmissing-prototypes]
drivers/gpu/drm/panfrost/panfrost_perfcnt.c:190:5: warning: no previous prototype for ‘panfrost_ioctl_perfcnt_enable’ [-Wmissing-prototypes]
drivers/gpu/drm/panfrost/panfrost_perfcnt.c:218:5: warning: no previous prototype for ‘panfrost_ioctl_perfcnt_dump’ [-Wmissing-prototypes]
drivers/gpu/drm/panfrost/panfrost_perfcnt.c:250:6: warning: no previous prototype for ‘panfrost_perfcnt_close’ [-Wmissing-prototypes]
drivers/gpu/drm/panfrost/panfrost_perfcnt.c:264:5: warning: no previous prototype for ‘panfrost_perfcnt_init’ [-Wmissing-prototypes]
drivers/gpu/drm/panfrost/panfrost_perfcnt.c:320:6: warning: no previous prototype for ‘panfrost_perfcnt_fini’ [-Wmissing-prototypes]
drivers/gpu/drm/panfrost/panfrost_mmu.c:227:6: warning: no previous prototype for ‘panfrost_mmu_flush_range’ [-Wmissing-prototypes]
drivers/gpu/drm/panfrost/panfrost_mmu.c:435:5: warning: no previous prototype for ‘panfrost_mmu_map_fault_addr’ [-Wmissing-prototypes]
For file panfrost_mmu.c, make functions static to fix this.
For file panfrost_perfcnt.c, include head file can fix this.
