Date: Tue, 31 Mar 2020 17:09:55 +0200
Subject: [PATCH] Add fixes for 5.6 kernel
Origin: https://salsa.debian.org/Herrie82-guest/broadcom-sta/-/merge_requests/1
Use ioremap instead of ioremap_nocache and proc_ops instead of
file_operations on Linux kernel 5.6 and above.
<rosh> Patch amended to adapt i386 arch.
