From bd5d21310133921021d78995ad6346f908483124 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Sun, 20 Nov 2016 16:09:30 +0100 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.
