[PATCH 3/3] PCI: tegra: make const array err_msg static

From: Christophe JAILLET
Date: Tue May 04 2021 - 13:18:27 EST


Don't populate the array err_msg on the stack but instead make it
static. Makes the object code smaller by 64 bytes.

While at it, add a missing const, as reported by checkpatch.

Compiled with gcc 11.0.1

Before:
$ size drivers/pci/controller/pci-tegra.o
text data bss dec hex filename
25623 2844 32 28499 6f53 drivers/pci/controller/pci-tegra.o

After:
$ size drivers/pci/controller/pci-tegra.o
text data bss dec hex filename
25559 2844 32 28435 6f13 drivers/pci/controller/pci-tegra.o
