From c5e46f7ad43b0519980020378a2b00b339359968 Mon Sep 17 00:00:00 2001 From: Martin Wilck Date: Wed, 14 Jun 2023 12:36:12 +0200 Subject: [PATCH] scsi: core: Merge scsi_internal_device_block() and device_block() scsi_internal_device_block() is only called from device_block(). Merge the two functions, and call the result scsi_device_block(), as the name device_block() is confusingly generic.
