PNP: ACPI: Fix string truncation warning
LKP reports below warning when building for RISC-V. drivers/pnp/pnpacpi/core.c:253:17: warning: 'strncpy' specified bound 50 equals destination size [-Wstringop-truncation] This appears to be a valid issue since the destination string may not be null-terminated. To fix this, append the NUL explicitly after the strncpy(). Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202307241942.Rff2Nri5-lkp@intel.com/ Signed-off-by: Sunil V L <sunilvl@ventanamicro.com> Signed-off-by: Rafael J.
