Gustavo A. R. Silva 2defb94edb drm/i915: Mark expected switch fall-throughs ... In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/gpu/drm/i915/gem/i915_gem_mman.c: In function ‘i915_gem_fault’: drivers/gpu/drm/i915/gem/i915_gem_mman.c:342:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (!i915_terminally_wedged(i915)) ^ drivers/gpu/drm/i915/gem/i915_gem_mman.c:345:2: note: here case -EAGAIN: ^~~~ drivers/gpu/drm/i915/gem/i915_gem_pages.c: In function ‘i915_gem_object_map’: ./include/linux/compiler.h:78:22: warning: this statement may fall through [-Wimplicit-fallthrough=] # define unlikely(x) __builtin_expect(!!(x), 0) ^~~~~~~~~~~~~~~~~~~~~~~~~~ ./include/asm-generic/bug.h:136:2: note: in expansion of macro ‘unlikely’ unlikely(__ret_warn_on); \ ^~~~~~~~ drivers/gpu/drm/i915/i915_utils.h:49:25: note: in expansion of macro ‘WARN’ #define MISSING_CASE(x) WARN(1, "Missing case (%s == %ld)\n", \ ^~~~ drivers/gpu/drm/i915/gem/i915_gem_pages.c:270:3: note: in expansion of macro ‘MISSING_CASE’ MISSING_CASE(type); ^~~~~~~~~~~~ drivers/gpu/drm/i915/gem/i915_gem_pages.c:272:2: note: here case I915_MAP_WB: ^~~~ drivers/gpu/drm/i915/i915_gpu_error.c: In function ‘error_record_engine_registers’: ./include/linux/compiler.h:78:22: warning: this statement may fall through [-Wimplicit-fallthrough=] # define unlikely(x) __builtin_expect(!!(x), 0) ^~~~~~~~~~~~~~~~~~~~~~~~~~ ./include/asm-generic/bug.h:136:2: note: in expansion of macro ‘unlikely’ unlikely(__ret_warn_on); \ ^~~~~~~~ drivers/gpu/drm/i915/i915_utils.h:49:25: note: in expansion of macro ‘WARN’ #define MISSING_CASE(x) WARN(1, "Missing case (%s == %ld)\n", \ ^~~~ drivers/gpu/drm/i915/i915_gpu_error.c:1196:5: note: in expansion of macro ‘MISSING_CASE’ MISSING_CASE(engine->id); ^~~~~~~~~~~~ drivers/gpu/drm/i915/i915_gpu_error.c:1197:4: note: here case RCS0: ^~~~ drivers/gpu/drm/i915/display/intel_dp.c: In function ‘intel_dp_get_fia_supported_lane_count’: ./include/linux/compiler.h:78:22: warning: this statement may fall through [-Wimplicit-fallthrough=] # define unlikely(x) __builtin_expect(!!(x), 0) ^~~~~~~~~~~~~~~~~~~~~~~~~~ ./include/asm-generic/bug.h:136:2: note: in expansion of macro ‘unlikely’ unlikely(__ret_warn_on); \ ^~~~~~~~ drivers/gpu/drm/i915/i915_utils.h:49:25: note: in expansion of macro ‘WARN’ #define MISSING_CASE(x) WARN(1, "Missing case (%s == %ld)\n", \ ^~~~ drivers/gpu/drm/i915/display/intel_dp.c:233:3: note: in expansion of macro ‘MISSING_CASE’ MISSING_CASE(lane_info); ^~~~~~~~~~~~ drivers/gpu/drm/i915/display/intel_dp.c:234:2: note: here case 1: ^~~~ drivers/gpu/drm/i915/display/intel_display.c: In function ‘check_digital_port_conflicts’: CC [M] drivers/gpu/drm/nouveau/nvkm/engine/disp/cursgv100.o drivers/gpu/drm/i915/display/intel_display.c:12043:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (WARN_ON(!HAS_DDI(to_i915(dev)))) ^ drivers/gpu/drm/i915/display/intel_display.c:12046:3: note: here case INTEL_OUTPUT_DP: ^~~~ Also, notice that the Makefile is modified to stop ignoring fall-through warnings. The -Wimplicit-fallthrough option will be enabled globally in v5.3. Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
