Subject: [PATCH 23/64] drm/amd/pm: Use struct_group() for memcpy() region
Date: Tue, 27 Jul 2021 13:58:14 -0700	[thread overview]
Message-ID: <20210727205855.411487-24-keescook@chromium.org> (raw)
In-Reply-To: <20210727205855.411487-1-keescook@chromium.org>

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.

Use struct_group() in structs:
	struct atom_smc_dpm_info_v4_5
	struct atom_smc_dpm_info_v4_6
	struct atom_smc_dpm_info_v4_7
	struct atom_smc_dpm_info_v4_10
	PPTable_t
so the grouped members can be referenced together. This will allow
memcpy() and sizeof() to more easily reason about sizes, improve
readability, and avoid future warnings about writing beyond the end of
the first member.

"pahole" shows no size nor member offset changes to any structs.
"objdump -d" shows no object code changes.
