[PATCH v6 8/8] selftests/resctrl: Fix wrong format specifier

From: Maciej Wieczor-Retman
Date: Fri Oct 13 2023 - 07:38:19 EST


Compiling resctrl selftest after adding a __printf() attribute to
ksft_print_msg() exposes -Wformat warning in show_cache_info().
The format specifier used expects a variable of type int but a long
unsigned int variable is passed instead.

Change the format specifier to match the passed variable.
