One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in struct openpromio. Address the following warning found after building (with GCC-13) sparc with sparc64_defconfig: In function 'opromgetprop', inlined from 'openprom_sunos_ioctl.isra' at drivers/sbus/char/openprom.c:312:11: drivers/sbus/char/openprom.c:141:24: warning: array subscript 1 is above array bounds of 'char[1]' [-Warray-bounds=] 141 | op->oprom_array[len] = '\0'; | ~~~~~~~~~~~~~~~^~~~~ In file included from drivers/sbus/char/openprom.c:31: arch/sparc/include/uapi/asm/openpromio.h: In function 'openprom_sunos_ioctl.isra': arch/sparc/include/uapi/asm/openpromio.h:16:17: note: while referencing 'oprom_array' 16 | char oprom_array[1]; /* Holds property names and values. */ | ^~~~~~~~~~~ This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -Warray-bounds. This results in no differences in binary output.
