From 3c47d19ff4dccf1500c33bcbe3b5bc804907a0da Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Thu, 11 Jan 2018 09:36:38 +0100 Subject: drivers: base: add coredump driver ops This adds the coredump driver operation. When the driver defines it a coredump file is added in the sysfs folder of the device upon driver binding. The file is removed when the driver is unbound. User-space can trigger a coredump for this device by echo'ing to the coredump file.
