Get rid of the > local variable and return 0 right when we get a successful result. This makes it > so we can return -ETIMEDOUT if we ever exit the loop because we know the > timeout time has been hit. > > Signed-off-by: Brett Creeley <brett.creeley@intel.com> > Signed-off-by: Anirudh Venkataramanan > <anirudh.venkataramanan@intel.com> > --- > drivers/net/ethernet/intel/ice/ice_lib.c | 11 ++++------- > 1 file changed, 4 insertions(+), 7 deletions(-) Tested-by: Andrew Bowers <andrewx.bowers@intel.com>
