From b6dfb2477fb0bf48e31999d306d2552144891f6e Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 3 Jun 2019 14:23:09 +0200 Subject: compat_ioctl: move WDIOC handling into wdt drivers All watchdog drivers implement the same set of ioctl commands, and fortunately all of them are compatible between 32-bit and 64-bit architectures. Modern drivers always go through drivers/watchdog/wdt.c as an abstraction layer, but older ones implement their own file_operations on a character device for this. Move the handling from fs/compat_ioctl.c into the individual drivers. Note that most of the legacy drivers will never be used on 64-bit hardware, because they are for an old 32-bit SoC implementation, but doing them all at once is safer than trying to guess which ones do or do not need the compat_ioctl handling.
