commit cd5048353725f37746da231202feaf5b88ceb46a Author: Nicola Vetrini <nicola.vetrini@xxxxxxxxxxx> AuthorDate: Fri Jul 21 08:30:29 2023 +0200 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Fri Jul 21 08:30:29 2023 +0200 xen: address MISRA C:2012 Rule 4.1 MISRA C:2012 Rule 4.1 has the following headline: "Octal and hexadecimal escape sequences shall be terminated." The string literals modified by this patch contain octal or hexadecimal escape sequences that are neither terminated by the end of the literal, nor by the beginning of another escape sequence. Therefore, such unterminated sequences have been split into a separate literal as a way to comply with the rule and preserve the semantics of the code. No functional changes.
