Subject: [POWERPC] bootwrapper: Modify *pp, not *p, in ft_shuffle().
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9dd2c31ab89a12571db89648bcc9992cf71b63d8;p=linux-beck.git

[POWERPC] bootwrapper: Modify *pp, not *p, in ft_shuffle().

Move the caller's pointer back to match the change in the region's start,
rather than alter a byte of the device tree's content.
