Subject: [PATCH 146/203] mtd: nand: pxa3xx: Remove READ0 switch/case
|
|
falltrough
|
|
|
|
READ0 and READOOB command preparation has a falltrough to SEQIN
|
|
case, where the command address is specified.
|
|
This is certainly confusing and makes the code less readable with
|
|
no added value. Let's remove it.
