cxgb4: fix usage of uninitialized variable
drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c: In function ‘init_one’: drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:4579:8: warning: ‘chip’ may be used uninitialized in this function [-Wmaybe-uninitialized] chip |= CHELSIO_CHIP_CODE(CHELSIO_T4, pl_rev); ^ drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:4571:11: note: ‘chip’ was declared here int ver, chip; ^ Fixes: d86bd29e0b31 ("cxgb4/cxgb4vf: read the correct bits of PL Who Am I register") Signed-off-by: Francois Romieu <romieu@fr.zoreil.com> Cc: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S.
