firmware: ti_sci: fix strncat length check
gcc-7 notices that the length we pass to strncat is wrong: drivers/firmware/ti_sci.c: In function 'ti_sci_probe': drivers/firmware/ti_sci.c:204:32: error: specified bound 50 equals the size of the destination [-Werror=stringop-overflow=] Instead of the total length, we must pass the length of the remaining space here. Fixes: aa276781a64a ("firmware: Add basic support for TI System Control Interface (TI-SCI) protocol") Cc: stable@vger.kernel.org Acked-by: Nishanth Menon <nm@ti.com> Acked-by: Santosh Shilimkar <ssantosh@kernel.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
