Subject: mtd: Fix trx check after partition rename ("linux" to "firmware")
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=766dff74457d9788a96ae9c8a3607c8e5c4081e2;p=librecmc%2Flibrecmc.git

mtd: Fix trx check after partition rename ("linux" to "firmware")

On brcm47xx (Huawei E970), I noticed that sysupgrade now tries to flash trx images which don't fit into the flash, resulting in non-booting system.

I found that mtd does trx size checking only when flashing to a partition called "linux". This patch changes this to be "firmware".

This matches the following patch which changed partition name in bcm47xxpart.c driver to "firmware":
