net: ipv6: unexport __init-annotated seg6_hmac_net_init()
As of commit 5801f064e351 ("net: ipv6: unexport __init-annotated seg6_hmac_init()"), EXPORT_SYMBOL and __init is a bad combination because the .init.text section is freed up after the initialization. Hence, modules cannot use symbols annotated __init. The access to a freed symbol may end up with kernel panic. This remove the EXPORT_SYMBOL to fix modpost warning: WARNING: modpost: vmlinux.o(___ksymtab+seg6_hmac_net_init+0x0): Section mismatch in reference from the variable __ksymtab_seg6_hmac_net_init to the function .init.text:seg6_hmac_net_init() The symbol seg6_hmac_net_init is exported and annotated __init Fix this by removing the __init annotation of seg6_hmac_net_init or drop the export.
