Subject: mm: vmalloc: remove redundant assignment in unmap_kernel_range_noflush()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1a69a623d98397e3968a3bd6e9f650e8a5e8fdce;p=linux.git

mm: vmalloc: remove redundant assignment in unmap_kernel_range_noflush()

'addr' is set to 'start' and then a few lines afterwards 'start' is set to
'addr'.  Remove the second asignment.
