Subject: [i-g-t V2 1/6] lib/igt_kms: New helper to check force joiner status
Date: Thu, 18 Apr 2024 14:49:54 +0530 [thread overview]
Message-ID: <20240418091959.781560-2-bhanuprakash.modem@intel.com> (raw)
In-Reply-To: <20240418091959.781560-1-bhanuprakash.modem@intel.com>
Add a new function to check the force joiner status
on selected connecter, so that it would be helpful to
check the force joiner status from other places too.
V2: - Add few debug prints
