mtd: do not use mtd->block_markbad directly

2012-01-09T18:26:26+00:00

Instead, use the new 'mtd_can_have_bb()', or just rely on 'mtd_block_markbad()'
return code, which will be -EOPNOTSUPP if bad blocks are not supported.

mtd: do not use mtd->sync directly

2012-01-09T18:26:21+00:00

This patch teaches 'mtd_sync()' to do nothing when the MTD driver does
not have the '->sync()' method, which allows us to remove all direct
'mtd->sync' accesses.

mtd: harmonize mtd_writev usage

2012-01-09T18:26:19+00:00

This patch makes the 'mtd_writev()' function more usable and logical. We first
teach it to fall-back to the 'default_mtd_writev()' function if the MTD driver
does not define its own '->writev()' method. Then we make block2mtd and JFFS2
just 'mtd_writev()' instead of 'default_mtd_writev()' function. This means we
can now stop exporting 'default_mtd_writev()' and instead, export
'mtd_writev()'. This is much cleaner and more logical, as well as allows us to
get read of another direct 'mtd->writev' access in JFFS2.

mtd: do use mtd->point directly

2012-01-09T18:26:09+00:00

Remove direct usage of the "mtd->point" function pointer. Instead,
test the mtd_point() return code for '-EOPNOTSUPP'.

jffs: remove custom mtd_fake_writev function

2012-01-09T18:26:04+00:00

Instead, use 'default_mtd_writev()' function which MTD provides.
