Subject: [PATCH 139/203] mtd: nand: pxa3xx: Add a nice comment to
|
||
|
pxa3xx_set_datasize()
|
||
|
|
||
|
Add a comment clarifying the use of pxa3xx_set_datasize() which is only
|
||
|
applicable on data read/write commands (i.e. commands with a data cycle,
|
||
|
such as READID, READ0, STATUS, etc.)
