From 661803b23330daa7839680cca43ab410955c3f10 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Tue, 20 Nov 2018 11:57:19 +0100 Subject: mtd: rawnand: Stop using chip->state in drivers We are about to simplify the locking in the rawnand framework, and part of this simplication is about getting rid of chip->state, so let's first patch drivers that check the state. All of them do that to get a timeout value based on the operation that is being executed. Since a timeout is, by definition, something that is here to prevent hanging on an event that might never happen, picking the maximum timeout value no matter the operation should be harmless.
