From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The variable region_start is assigned twice, the first value is
never read and redundant, so can be removed. We can clean up the
code further by assigning rg_start directly rather than using the
temporary variable region_start which can then be removed. Cleans
up the clang warning:
drivers/hv/hv_balloon.c:976:3: warning: Value stored to 'region_start'
is never read
