commit 3ce4a03852d6dd3fd28c2fb2ee9f89bb9ccf9a9b upstream.
shift_param is defined and set in iwl_pcie_load_cpu_sections but not
used. Fix this to avoid -Wunused-but-set-variable warning.
The code using it turned into dead code with commit dcab8ecd5617
("iwlwifi: mvm: support ucode load for family_8000 B0 only") which
added a separate function iwl_pcie_load_given_ucode_8000 (then 8000b)
for IWL_DEVICE_FAMILY_8000. Commit 76f8c0e17edc ("iwlwifi: pcie:
remove dead code") removed the dead code but left shift_param as is.
iwlwifi/pcie/trans.c: In function ‘iwl_pcie_load_cpu_sections’:
iwlwifi/pcie/trans.c:871:6: warning: variable ‘shift_param’ set but not used [-Wunused-but-set-variable]
Fixes: dcab8ecd5617 ("iwlwifi: mvm: support ucode load for family_8000 B0 only")
Fixes: 76f8c0e17edc ("iwlwifi: pcie: remove dead code")
