Subject: [POWERPC] boot: Simplify gunzip_finish
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=51a505d73bfed863135861fdc0496a09766b69d5;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[POWERPC] boot: Simplify gunzip_finish

Call gunzip_partial to calculate the remaining length and copy the
data to the user buffer.  This makes it shorter and reduces
duplication.
