[ Upstream commita3403d3047] gcc -Wstringop-truncation warns about copying a string that results in a missing nul termination: drivers/acpi/acpica/tbfind.c: In function 'acpi_tb_find_table': drivers/acpi/acpica/tbfind.c:60:9: error: 'strncpy' specified bound 6 equals destination size [-Werror=stringop-truncation] 60 | strncpy(header.oem_id, oem_id, ACPI_OEM_ID_SIZE); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/acpi/acpica/tbfind.c:61:9: error: 'strncpy' specified bound 8 equals destination size [-Werror=stringop-truncation] 61 | strncpy(header.oem_table_id, oem_table_id, ACPI_OEM_TABLE_ID_SIZE); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The code works as intended, and the warning could be addressed by using a memcpy(), but turning the warning off for this file works equally well and may be easier to merge.
