[PATCH v3 00/11] Fix NAND controllers probe functions error path

[Miquel Raynal]

Hello all,

In order to remove the limitation that prevents dynamic allocations
during the identification phase (nand_scan_ident()), we need to get rid
of the nand_scan_ident()/nand_scan_tail() calls from drivers and only
export nand_scan().

This series prepares the migration to nand_scan() by first fixing (and
enhancing some times) the probe function error path of the drivers that
do not use nand_scan() yet.

The three main problems addressed in the series are:
0/ unproper error path (fuzzy, styling issues, undescriptive goto's).
1/ a wrong error path that does not free/disable the resources
   correctly.
2/ nand_cleanup() is not called upon error after a successful
   nand_scan_tail().
3/ nand_release() is called instead of nand_cleanup(). nand_release()
   does call nand_cleanup() and also mtd_device_unregister(), which
   should not be called while mtd_device_register() as succeeded.

Thanks,
Miquèl

Changes since v2:
=================
 * Reworked the few remaining patches that needed small changes.
 * docg4: changed the commit message as proposed.
 * fsl_elbc/fsl_ifc: moved the wrong nand_release() out of the
   'remove' function to avoid double free possible issues.
 * fsmc/hisi504/lpc32xx_mlc/lpc32xx_slc: split the changes in two
   commits, one to fix the goto labels/style, one that actually fixes
   the function.

Changes since v1:
=================
 * Extracted only the patches fixing the error path from the first huge
   series (50+ patches) that also converted the drivers to nand_scan().
 * Changed wrong nand_release() calls to nand_cleanup().
