soc: qcom: wcnss_ctrl: Avoid string overflow
[ Upstream commit 4c96ed170d658d8826d94edec8ac93ee777981a2 ]
'chinfo.name' is used as a NUL-terminated string, but using strncpy() with
the length equal to the buffer size may result in lack of the termination:
drivers//soc/qcom/wcnss_ctrl.c: In function 'qcom_wcnss_open_channel':
drivers//soc/qcom/wcnss_ctrl.c:284:2: warning: 'strncpy' specified bound 32 equals destination size [-Wstringop-truncation]
strncpy(chinfo.name, name, sizeof(chinfo.name));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This changes it to use the safer strscpy() instead.
