[PATCH] drm/amdkfd: Fix "-Wmisleading-indentation" warning

[sunpeng.li at amd.com]

From: Leo Li <sunpeng.li at amd.com>

The following warning is seen during compile:

./include/linux/idr.h:212:2: warning: this ‘for’ clause does not
guard... [-Wmisleading-indentation]
  for ((entry) = idr_get_next((idr), &(id));   \
  ^
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_events.c:1038:3: note: in
expansion of macro ‘idr_for_each_entry_continue’
   idr_for_each_entry_continue(&p->event_idr, ev, id)
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_events.c:1043:4: note: ...this
statement, but the latter is misleadingly indented as if it were guarded
by the ‘for’
    if (ev->type == KFD_EVENT_TYPE_MEMORY &&
    ^~

Place braces around the indented block, as seemingly intended.

Hi Eric,

This patch fixes the warning, but doesn't address a build error that
occurs if CONFIG_HSA_AMD is not set:

ERROR: "kgd2kfd_set_sram_ecc_flag" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
scripts/Makefile.modpost:92: recipe for target '__modpost' failed
make[1]: *** [__modpost] Error 1
Makefile:1260: recipe for target 'modules' failed
make: *** [modules] Error 2
make: *** Waiting for unfinished jobs....

Thanks,
Leo
