[PATCH 1/5] EDAC: Prefer 'unsigned int' to bare use of 'unsigned'
From: Robert Richter
Date: Mon Sep 02 2019 - 08:34:00 EST
Use of 'unsigned int' instead of bare use of 'unsigned'. Fix this for
edac_mc*, ghes and the i5100 driver.
Depending on the compiler's warning level it can throw messages like
this:
WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
#235: FILE: drivers/edac/i5100_edac.c:854:
+ const unsigned chan = i5100_csrow_to_chan(mci, dimm->idx);
