X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4498c80d9c1ebdf42837be6a52ead35a2aa2b819;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [BLUETOOTH]: Fix unaligned access in hci_send_to_sock. The "u16 *" derefs of skb->data need to be wrapped inside of a get_unaligned(). Thanks to Gustavo Zacarias for the bug report. Signed-off-by: David S.
