From 02ccfdcf4a397fc3ac0332c1a9c9dbb4d1385482 Mon Sep 17 00:00:00 2001 From: Gianluca Luparini Date: Wed, 12 Jul 2023 13:30:26 +0200 Subject: [PATCH] xen/pci: fix violations of MISRA C:2012 Rule 7.2 The xen sources contains violations of MISRA C:2012 Rule 7.2 whose headline states: "A 'u' or 'U' suffix shall be applied to all integer constants that are represented in an unsigned type". Add the 'U' suffix to integers literals with unsigned type and also to other literals used in the same contexts or near violations, when their positive nature is immediately clear. The latter changes are done for the sake of uniformity.
