[ Upstream commit fa0218ef733e6f247a1a3986e3eb12460064ac77 ]
kgdbts current fails when compiled with restrict:
drivers/misc/kgdbts.c: In function ‘configure_kgdbts’:
drivers/misc/kgdbts.c:1070:2: error: ‘strcpy’ source argument is the same as destination [-Werror=restrict]
strcpy(config, opt);
^~~~~~~~~~~~~~~~~~~
As the error says, config is being used in both the source and destination.
Refactor the code to avoid the extra copy and put the parsing closer to
the actual location.

[ Upstream commit b281218ad4311a0342a40cb02fb17a363df08b48 ]
There is an out-of-bounds access to "config[len - 1]" array when the
variable "len" is zero.
See commit dada6a43b040 ("kgdboc: fix KASAN global-out-of-bounds bug
in param_set_kgdboc_var()") for details.
