From 80c394fab89649585089f5bd5013f2d99e5756ef Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Thu, 11 Jun 2015 13:27:51 +0200 Subject: [PATCH] cxl: Add explicit precision specifiers C99 says that a precision given as simply '.' with no following digits or * should be interpreted as 0. The kernel's printf implementation, however, treats this case as if the precision was omitted. C99 also says that if both the precision and value are 0, no digits should be printed. Even if the kernel followed C99 to the letter, I don't think that would be particularly useful in these cases. For consistency with most other format strings in the file, use an explicit precision of 16 and add a 0x prefix.
