From eb9d673f94fb186702c4933ef72d190232c26ce9 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 28 Oct 2020 16:16:32 +0100 Subject: pinctrl: renesas: Reorder struct sh_pfc_pin to remove hole On arm64, pointer size and alignment is 64-bit, hence a 4-byte hole is present in between the enum_id and name members of the sh_pfc_pin structure. Get rid of this hole by sorting the structure's members by decreasing size. This saves up to 1.5 KiB per enabled SoC, and reduces the size of a kernel including support for all R-Car Gen3 SoCs by more than 10 KiB. This has no size impact on SH and arm32.
