Subject: kernel: print and reset grub_errno after each embedded config line
X-Git-Tag: 2.02-beta3~155
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=609c049dcc318fae3af1ba29f0ceb348172769f0;p=thirdparty%2Fgrub.git

kernel: print and reset grub_errno after each embedded config line

Otherwise it causes subsequent file open to fail, because grub_file_open
misinterprets set grub_errno for grub_file_get_device_name failure.

Closes: 46540
