From: Stafford Horne Date: Sun, 26 Jul 2020 03:11:54 +0000 (+0900) Subject: io: Fix return type of _inb and _inl X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=214ba3584b2e2c57536fa8aed52521ac59c5b448;p=linux.git io: Fix return type of _inb and _inl The return type of functions _inb, _inw and _inl are all u16 which looks wrong. This patch makes them u8, u16 and u32 respectively. The original commit text for these does not indicate that these should be all forced to u16.
