Subject: block: don't return 1 for the fallback case in blkdev_get_zone_info
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=86a9ce21f5b781c56eba23cbbd2264ab74778ab0;p=thirdparty%2Flinux.git

block: don't return 1 for the fallback case in blkdev_get_zone_info

blkdev_do_report_zones returns the number of reported zones, but
blkdev_get_zone_info returns 0 or an errno.  Translate to the expected
return value in blkdev_report_zone_fallback.

Fixes: b037d41762fd ("block: introduce blkdev_get_zone_info()")
