Subject: net: dsa: mv88e6xxx: allocate the number of ports
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=73b1204d070d2970749beb3fa3ca6e639dc7a3b6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net: dsa: mv88e6xxx: allocate the number of ports

The current code allocates DSA_MAX_PORTS ports for a Marvell dsa_switch
structure. Provide the exact number of ports so the corresponding
ds->num_ports is accurate.
