Subject: [PATCH] mtd: bcm47xxpart: fix parsing first block after aligned TRX

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.
