Subject: [PATCH v2 01/14] drm/msm/dp: set safe_to_exit_level before
 printing it

Rather than printing random garbage from stack and pretending that it is
the default safe_to_exit_level, set the variable beforehand.

Fixes: d13e36d7d222 ("drm/msm/dp: add audio support for Display Port on MSM")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202411081748.0PPL9MIj-lkp@intel.com/
