   4 Subject: [PATCH 146/203] mtd: nand: pxa3xx: Remove READ0 switch/case
   5  falltrough
   6
   7 READ0 and READOOB command preparation has a falltrough to SEQIN
   8 case, where the command address is specified.
   9 This is certainly confusing and makes the code less readable with
  10 no added value. Let's remove it.
