SubjectRe: [PATCH v2 3/3] mtd: nand: squash struct nand_buffers into struct nand_chip
2017-12-05 17:47 GMT+09:00 Masahiro Yamada <yamada.masahiro@socionext.com>:
> struct nand_buffers is malloc'ed in nand_scan_tail() just for
> containing three pointers. Squash this struct into nand_chip.

> Move and rename as follows:
>
> chip->buffers->ecccalc -> chip->ecc.calc_buf
> chip->buffers->ecccode -> chip->ecc.code_buf
> chip->buffers->databuf -> chip->data_buf
