Subject: bridge: sparse fixes in br_ip6_multicast_alloc_query()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=53631a5f9c6669264adb7b4e92fd95d1d6ffa7d3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

bridge: sparse fixes in br_ip6_multicast_alloc_query()

Changed type of csum field in struct igmpv3_query from __be16 to
__sum16 to eliminate type warning, made same change in struct
igmpv3_report for consistency.

Fixed up an ntohs() where htons() should have been used instead.
