| Subject: drm/bridge: tc358768: remove unused variable |
| |
| From: Francesco Dolcini <francesco.dolcini@toradex.com> |
| |
| [ Upstream commit e4a5e4442a8065c6959e045c061de801d545226d ] |
| |
| 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. |
