of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: lib/decompress: use designated initializers for struct compress_format
Date: Thu, 11 Sep 2025 01:23:51 +0200

Switch 'compressed_formats[]' to the more modern and flexible designated
initializers.  This improves readability and allows struct fields to be
reordered.  Also use a more concise sentinel marker.

Remove the curly braces around the for loop while we're at it.

No functional changes intended.
