[PATCH] mxc_nand: fix PM

From: Uwe Kleine-König <hidden>
Date: 2010-06-14 08:43:51

Hello Eric,

On Thu, May 27, 2010 at 07:55:19PM +0200, Eric B?nard wrote:
* when resuming, we get the following log :
nand_resume called for a chip which is not in suspended state
* this happens because mtd->suspend and mtd->resume are already
called from the mtd layer, thus they were called a second time
in mxc_nand so mtd complains when trying to resume for the
second time
* the fix is to remove these call and thus remove the supend and
resume functions of mxc_nand
the commit log looks IMHO ugly.  Better make it (including Subject):

mtd/mxc_nand: don't call mtd->{suspend,resume} explicitly

The mtd layer is responsible to call mtd->{suspend,resume}.  Doing it
again in the driver is wrong and results in a warning:

	nand_resume called for a chip which is not in suspended state

at resume time.  Removing the calls from the resume and suspend
functions makes them empty allowing them to be deleted completely.
