Subject: [PATCH v4 1/3] efi/cper: Adjust infopfx size to accept an extra space
Compiling with W=1 with werror enabled produces an error:
drivers/firmware/efi/cper-arm.c: In function ‘cper_print_proc_arm’:
drivers/firmware/efi/cper-arm.c:298:64: error: ‘snprintf’ output may be truncated before the last format character [-Werror=format-truncation=]
298 | snprintf(infopfx, sizeof(infopfx), "%s ", newpfx);
| ^
drivers/firmware/efi/cper-arm.c:298:25: note: ‘snprintf’ output between 2 and 65 bytes into a destination of size 64
298 | snprintf(infopfx, sizeof(infopfx), "%s ", newpfx);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
As the logic there adds an space at the end of infopx buffer.
Add an extra space to avoid such warning.
