From 46d57a7a8e331ad402783a77d246c4196ba21863 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 3 Jul 2023 17:58:38 +0300 Subject: [PATCH] docs: printk-formats: Fix hex printing of signed values The commit cbacb5ab0aa0 ("docs: printk-formats: Stop encouraging use of unnecessary %h[xudi] and %hh[xudi]") obviously missed the point of sign promotion for the signed values lesser than int. In such case %x prints not the same as %h[h]x. Restore back those specifiers for the signed hex cases.
