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.
