SubjectCoverity: genphy_c45_plca_set_cfg(): UNINIT
Hello!

This is an experimental semi-automated report about issues detected by
Coverity from a scan of next-20230113 as part of the linux-next scan project:
https://scan.coverity.com/projects/linux-next-weekly-scan

You're getting this email because you were associated with the identified
lines of code (noted below) that were touched by commits:

Wed Jan 11 08:35:02 2023 +0000
493323416fed ("drivers/net/phy: add helpers to get/set PLCA configuration")

Coverity reported the following:

*** CID 1530573: (UNINIT)
drivers/net/phy/phy-c45.c:1036 in genphy_c45_plca_set_cfg()
1030 return ret;
1031
1032 val = ret;
1033 }
1034
1035 if (plca_cfg->node_cnt >= 0)
vvv CID 1530573: (UNINIT)
vvv Using uninitialized value "val".
1036 val = (val & ~MDIO_OATC14_PLCA_NCNT) |
1037 (plca_cfg->node_cnt << 8);
1038
1039 if (plca_cfg->node_id >= 0)
1040 val = (val & ~MDIO_OATC14_PLCA_ID) |
1041 (plca_cfg->node_id);
drivers/net/phy/phy-c45.c:1076 in genphy_c45_plca_set_cfg()
1070 return ret;
1071
1072 val = ret;
1073 }
1074
1075 if (plca_cfg->burst_cnt >= 0)
vvv CID 1530573: (UNINIT)
vvv Using uninitialized value "val".
1076 val = (val & ~MDIO_OATC14_PLCA_MAXBC) |
1077 (plca_cfg->burst_cnt << 8);
1078
1079 if (plca_cfg->burst_tmr >= 0)
1080 val = (val & ~MDIO_OATC14_PLCA_BTMR) |
1081 (plca_cfg->burst_tmr);

If this is a false positive, please let us know so we can mark it as
such, or teach the Coverity rules to be smarter. If not, please make
sure fixes get into linux-next. :) For patches fixing this, please
include these lines (but double-check the "Fixes" first):

Reported-by: coverity-bot <keescook+coverity-bot@chromium.org>
Addresses-Coverity-ID: 1530573 ("UNINIT")
Fixes: 493323416fed ("drivers/net/phy: add helpers to get/set PLCA configuration")

Thanks for your attention!
