The DPLL_CLOCK_QUALITY_LEVEL_ITU_OPT1_EPRC is not reported via netlink
due to bug in dpll_msg_add_clock_quality_level(). The usage of
DPLL_CLOCK_QUALITY_LEVEL_MAX for both DECLARE_BITMAP() and
for_each_set_bit() is not correct because these macros requires bitmap
size and not the highest valid bit in t... | ```diff

A NULL pointer dereference can occur in tcp_ao_finish_connect() during a
connect() system call on a socket with a TCP-AO key added and TCP_REPAIR
enabled.
The function is called with skb being NULL and attempts to dereference it
on tcp_hdr(skb)->seq without a prior skb validation.
Fix this by checkin... | ```diff

Changes to the stmmac driver to fix various issues with PTP have made
stmmac_init_ptp() less about initialising the entire PTP block, and
now primarily deals with the packet timestamping support. The exception
to this is ptp_clk_freq_config(), which is an odditiy. It remains
