From 23fc539e81295b14b50c6ccc5baeb4f3d59d822d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 14 Feb 2022 20:22:10 +0100 Subject: uaccess: fix type mismatch warnings from access_ok() On some architectures, access_ok() does not do any argument type checking, so replacing the definition with a generic one causes a few warnings for harmless issues that were never caught before. Fix the ones that I found either through my own test builds or that were reported by the 0-day bot.
