Subject: [PATCH] mfd: t7l66xb: Drop platform disable callback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
[ Upstream commit 128ac294e1b437cb8a7f2ff8ede1cde9082bddbe ]
None of the in-tree instantiations of struct t7l66xb_platform_data
provides a disable callback. So better don't dereference this function
pointer unconditionally. As there is no user, drop it completely instead
of calling it conditional.
This is a preparation for making platform remove callbacks return void.
