staging: rtl8712: reduce stack usage, again
An earlier patch I sent reduced the stack usage enough to get
below the warning limit, and I could show this was safe, but with
GCC_PLUGIN_STRUCTLEAK_BYREF_ALL, it gets worse again because large stack
variables in the same function no longer overlap:
drivers/staging/rtl8712/rtl871x_ioctl_linux.c: In function 'translate_scan.isra.2':
drivers/staging/rtl8712/rtl871x_ioctl_linux.c:322:1: error: the frame size of 1200 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
Split out the largest two blocks in the affected function into two
separate functions and mark those noinline_for_stack.
Fixes: 8c5af16f7953 ("staging: rtl8712: reduce stack usage")
Fixes: 81a56f6dcd20 ("gcc-plugins: structleak: Generalize to all variable types")
