net: fix sparse warnings in SNMP_UPD_PO_STATS(_BH)
ptr used to be a non __percpu pointer (result of a this_cpu_ptr assignment, 7d720c3e4f0c4 ("percpu: add __percpu sparse annotations to net")). Since d25398df59b56 ("net: avoid reloads in SNMP_UPD_PO_STATS"), that's no longer the case, SNMP_UPD_PO_STATS uses this_cpu_add and ptr is now __percpu. Silence sparse warnings by preserving the original type and annotation, and remove the out-of-date comment. warning: incorrect type in initializer (different address spaces) expected unsigned long long *ptr got unsigned long long [noderef] <asn:3>*<noident> warning: incorrect type in initializer (different address spaces) expected void const [noderef] <asn:3>*__vpp_verify got unsigned long long *<noident> warning: incorrect type in initializer (different address spaces) expected void const [noderef] <asn:3>*__vpp_verify got unsigned long long *<noident> Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Acked-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S.
