[PATCH 0/7] mtd: nand: pxa3xx cleanup

[PATCH 0/7] mtd: nand: pxa3xx cleanup

[Ezequiel Garcia]

This is a small set of cleanups for pxa3xx. Tested by compilation only.

Although the patches are somewhat simple, it would be wise to have some
testing before applying them.

Any feedback welcome!

[PATCH 2/7] mtd: nand: pxa3xx: Use devm_kzalloc

[Ezequiel Garcia]

Replace regular kzalloc with managed devm_kzalloc
which simplifies the error path.

clk_disable_unprepare variants as required by common clock framework.

[PATCH 7/7] mtd: nand: pxa3xx: Move buffer release code to its own function

[Ezequiel Garcia]

Create a function to release the buffer and the dma channel, thus undoing
what pxa3xx_nand_init_buff() did. This commit makes the code more readable
and will allow to handle non-DMA capable platforms easier.

Of course, this first patch does not belong to this series
(it's just an intruder), so please omit it.

Looks OK to me, but I'd like to compile-test it before applying. Would
you please send me a defconfig that I can use for compile-testing?

Sure. The below is a very minimal config that allows to compile this
driver (of course, it won't boot on any machine).
