[dpdk-dev] [PATCH v4 27/38] net/ice/base: fix Klockwork analysis reported issues

[Qi Zhang]

Klocwork points out some code is unreachable in
ice_get_itr_intrl_gran and ice_ptg_find_ptype.
The patch removed the unreachable code and resolved the static
analysis reported issues.

Fixes: 51d04e4933e3 ("net/ice/base: add flexible pipeline module")
Fixes: 453d087ccaff ("net/ice/base: add common functions")
