- Subject: [PATCH] mtd: bcm47xxpart: fix parsing first block after aligned TRX
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- After parsing TRX we should skip to the first block placed behind it.
- Our code was working only with TRX with length not aligned to the
- blocksize. In other cases (length aligned) it was missing the block
- places right after TRX.
- This fixes calculation and simplifies the comment.
