[PATCH 1/3] mtd: nand: remove EXPORT_SYMBOL of nand_scan_bbt()

[PATCH 1/3] mtd: nand: remove EXPORT_SYMBOL of nand_scan_bbt()

[Thomas Petazzoni]

Since commit 17799359e7b3fa6ef4f2bf926cd6821cf7903ecf ("mtd: nand_bbt:
make nand_scan_bbt() static"), the nand_scan_bbt() function is marked
as static but is still exported using EXPORT_SYMBOL(), which doesn't
make much sense.

This commit gets rid of the useless EXPORT_SYMBOL.

[PATCH 2/3] mtd: onenand: make onenand_scan_bbt() static

[Thomas Petazzoni]

Like was done in commit 17799359e7b3fa6ef4f2bf926cd6821cf7903ecf
("mtd: nand_bbt: make nand_scan_bbt() static") for the NAND code, this
commit makes the onenand_scan_bbt() function static in the OneNAND
code, since it is only used in onenand_bbt.c itself.

Consequently, the EXPORT_SYMBOL() and declaration in bbm.h are also
removed.

[PATCH 3/3] mtd: onenand: unexport onenand_default_bbt()

[Thomas Petazzoni]

The onenand_default_bbt() function is only used by the OneNAND core
and not by drivers, so there is no real need to export
it. Additionally, the corresponding nand_default_bbt() for regular
NANDs is not exported either, so for consistency reasons, this commit
removes the EXPORT_SYMBOL on onenand_default_bbt().

Hehe, I noticed this useless EXPORT_SYMBOL while reviewing the BBT
rework, just forgot to post the patch removing it.

Not sure how this will impact the BBT rework done by Peter, but those
are trivial changes, so I guess it should be pretty easy to fix the
conflicts in case Brian decides to take them before the BBT rework
changes.
