From: Jesse Brandeburg Date: Mon, 12 Oct 2020 18:13:46 +0000 (-0700) Subject: e1000: remove unused and incorrect code X-Git-Tag: io_uring-5.10-2020-10-20~32^2~7^2 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=f2bf814a27c567abd51683e1e853ff3b5bbf9186;p=linux-2.6-block.git e1000: remove unused and incorrect code The e1000_clear_vfta function was triggering a warning in kbuild-bot testing. It's actually a bug but has no functional impact. drivers/net/ethernet/intel/e1000/e1000_hw.c:4415:58: warning: Same expression in both branches of ternary operator. [duplicateExpressionTernary] Fix this warning by removing the offending code and simplifying the routine to do exactly what it did before, no functional change.
