From: William Breathitt Gray Date: Tue, 24 Jan 2017 22:02:33 +0000 (-0500) Subject: watchdog: ebc-c384_wdt: Utilize devm_ functions in driver probe callback X-Git-Tag: v4.11-rc1~66^2~17 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=540aea3dbffc6a75d0b3b77db1cde36a065a6ab5;p=linux.git watchdog: ebc-c384_wdt: Utilize devm_ functions in driver probe callback The devm_ resource manager functions allow memory to be automatically released when a device is unbound. This patch takes advantage of the resource manager functions and replaces the watchdog_register_device call with the devm_watchdog_register_device call. In addition, the ebc_c384_wdt_remove function has been removed as no longer necessary due to the use of the relevant devm_ resource manager functions.
