Subject: Bluetooth: hidp: using strlcpy instead of strncpy, also beautify code.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=673e1dd7ed7701cac8c5c247d152fd3d2da2a4f1;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Bluetooth: hidp: using strlcpy instead of strncpy, also beautify code.

For NULL terminated string, need always let it ended by zero.

Since have already called memcpy() to initialize 'ci', so need not
redundant initialization.

Better use ''if(session->hid) {} else if(session->input) {}"" instead
of ''if(session->hid) {}; if(session->input) {};''
