Subject: dm exception store: fix exstore lookup to be case insensitive
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f6bd4eb73cdf2a5bf954e497972842f39cabb7e3;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

dm exception store: fix exstore lookup to be case insensitive

When snapshots are created using 'p' instead of 'P' as the
exception store type, the device-mapper table loading fails.

This patch makes the code case insensitive as intended and fixes some
regressions reported with device-mapper snapshots.
