Hi Sergio,

FYI:

$ make W=1 drivers/pci/
CC drivers/pci/controller/pcie-mt7621.o
drivers/pci/controller/pcie-mt7621.c: In function ‘mt7621_pcie_probe’:
drivers/pci/controller/pcie-mt7621.c:228:49: error: ‘snprintf’ output may be truncated before the last format character [-Werror=format-truncation=]
228 | snprintf(name, sizeof(name), "pcie-phy%d", slot);
| ^
drivers/pci/controller/pcie-mt7621.c:228:9: note: ‘snprintf’ output between 10 and 11 bytes into a destination of size 10
228 | snprintf(name, sizeof(name), "pcie-phy%d", slot);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I know we'll never actually hit this, but it'd be nice to clean this
up, and I don't think it would really cost us anything. I think it's
currently the only "W=1" warning in drivers/pci/.
