Merge branch 'net-fix-module_description-for-net-p5'

Breno Leitao says: ==================== net: Fix MODULE_DESCRIPTION() for net (p5) There are hundreds of network modules that misses MODULE_DESCRIPTION(), causing a warning when compiling with W=1. Example: WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_cmp.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_nbyte.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_u32.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_meta.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_text.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_canid.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/ip_tunnel.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/ipip.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/ip_gre.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/udp_tunnel.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/ip_vti.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/ah4.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/esp4.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/xfrm4_tunnel.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/tunnel4.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/xfrm/xfrm_algo.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/xfrm/xfrm_user.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv6/ah6.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv6/esp6.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv6/xfrm6_tunnel.o WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv6/tunnel6.o This part5 of the patchset focus on the missing net/ module, which are now warning free. v1: https://lore.kernel.org/all/20240205101400.1480521-1-leitao@debian.org/ v2: https://lore.kernel.org/all/20240207101929.484681-1-leitao@debian.org/ ==================== Link: https://lore.kernel.org/r/20240208164244.3818498-1-leitao@debian.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
