[PATCH 0/2] net/txgbe: fix coverity issues

[Zaiyu Wang]

This series fixes several Coverity issues reported against the txgbe
driver in the 26.07-rc2 release.

Patch 1 fixes a REVERSE_INULL issue (CID 504601) in
txgbe_dev_setup_link_alarm_handler_aml() by moving the null pointer
check before the pointer dereference.

Patch 2 fixes INTEGER_OVERFLOW (CID 504602) and BAD_SHIFT issues
(CIDs 504598, 504613) in the e56 backplane code by validating
lane_num at the source in txgbe_e56_cl72_training() before any
GENMASK operations are performed.

  net/txgbe: fix null pointer check order
