[merged mm-stable] mpage-convert-do_mpage_readpage-to-return-void-type.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mpage: convert do_mpage_readpage() to return void type
has been removed from the -mm tree.  Its filename was
     mpage-convert-do_mpage_readpage-to-return-void-type.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mpage: convert do_mpage_readpage() to return void type
Date: Fri, 29 Aug 2025 10:36:59 +0800

The return value of do_mpage_readpage() is arg->bio, which is already set
in the arg structure.  Returning it again is redundant.

This patch changes the return type to void since the caller doesn't care
about the return value.
