From 4edfabd9e40d72480418d4ce39228abd6c0f4f02 Mon Sep 17 00:00:00 2001 From: Robert Hancock Date: Tue, 18 Jun 2019 09:53:04 -0600 Subject: disk: part: Don't skip partition init blk_get_device_by_str was skipping part_init when hw partition 0 was selected because it is the default. However, this caused issues when switching to a non-zero partition and then back to partition zero, as stale data from the wrong partition was returned. Remove this optimization and call part_init regardless of the selected partition.
