From: Arnd Bergmann <arnd@xxxxxxxx> Passing a variable string as a printf style format is potentially dangerous that -Wformat-security can warn about if enabled.

The warning is enabled by default because there are still over 100 other files with the same problem. --- drivers/gpu/drm/msm/adreno/a6xx_gmu.c | 2 +- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 28 ++++++++++++++++--------- 2 files changed, 19 insertions(+), 11 deletions(-)
