From: Dan Carpenter Date: Sat, 19 Jun 2021 13:49:18 +0000 (+0300) Subject: net: hns3: fix a double shift bug X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=956c3ae411b2746c5018e0454909eb8c662b31ef;p=linux.git net: hns3: fix a double shift bug These flags are used to set and test bits like this: if (!test_bit(HCLGE_PTP_FLAG_TX_EN, &ptp->flags) || The issue is that test_bit() takes a bit number like 1, but we are passing BIT(1) instead and it's testing BIT(BIT(1)). This does not cause a problem because it is always done consistently and the bit values are very small.
