From e4a5e4442a8065c6959e045c061de801d545226d Mon Sep 17 00:00:00 2001 From: Francesco Dolcini <francesco.dolcini@toradex.com> Date: Thu, 27 Apr 2023 16:29:34 +0200 Subject: [PATCH] drm/bridge: tc358768: remove unused variable Remove the unused phy_delay_nsk variable, before it was wrongly used to compute some register value, the fixed computation is no longer using it and therefore can be removed.
