soc: qcom: apr: Avoid string overflow

Browse source

'adev->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:

In function 'apr_add_device',
    inlined from 'of_register_apr_devices' at drivers//soc/qcom/apr.c:264:7,
    inlined from 'apr_probe' at drivers//soc/qcom/apr.c:290:2:
drivers//soc/qcom/apr.c:222:3: warning: 'strncpy' specified bound 32 equals destination size [-Wstringop-truncation]
   strncpy(adev->name, np->name, APR_NAME_SIZE);
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This changes it to use the safer strscpy() instead.
