Subject: [PATCH 5.15 141/279] btrfs: make 1-bit bit-fields of scrub_page unsigned int

From: Colin Ian King <colin.i.king@...glemail.com>

[ Upstream commit d08e38b62327961295be1c63b562cd46ec97cd07 ]

The bitfields have_csum and io_error are currently signed which is not
recommended as the representation is an implementation defined
behaviour. Fix this by making the bit-fields unsigned ints.
