[ Upstream commit 4b09715f1504f1b6e8dff0e9643630610bc05141 ]
Tell snprintf() to store at most 10 bytes in the output buffer
instead of 30.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_debugfs.c:1508 dp_dsc_clock_en_read() error: snprintf() is printing too much 30 vs 10
Fixes: c06e09b76639 ("drm/amd/display: Add DSC parameters logging to debugfs")
