From 629de518e6f3b81bc1d7486a9b2e0a8fb100e18e Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Tue, 13 Apr 2021 12:57:14 +0200 Subject: [PATCH] media: atmel: atmel-isc: add his_entry to register offsets Add his_entry to the reg offsets struct. This will allow different products to have a different reg offset for this particular module.
