Subject: btrfs_read_block_groups: Use enums to index
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1095cc0d924e1c61fb34e0bfcec049d1fbcca77c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

btrfs_read_block_groups: Use enums to index

 btrfs_space_info->block_groups.

The current code uses integer literals to index
btrfs_space_info->block_groups[] array. Instead use corresponding
enums from 'enum btrfs_raid_types'.
