gcc-9: silence 'address-of-packed-member' warning
GCC 9.x starts complaining about potential misalignment of the pointer to the array (in this case alignment=2) in the packed (alignment=1) structures. Repeating Linus' Torvalds commit 6f303d60534c in the Linux kernel. Original commit message: We already did this for clang, but now gcc has that warning too. Yes, yes, the address may be unaligned. And that's kind of the point. This in particular hides the warnings like drivers/usb/gadget/composite.c:545:23: warning: taking address of packed member of ‘struct usb_string_descriptor’ may result in an unaligned pointer value [-Waddress-of-packed-member] 545 | collect_langs(sp, s->wData); drivers/usb/gadget/composite.c:550:24: warning: taking address of packed member of ‘struct usb_string_descriptor’ may result in an unaligned pointer value [-Waddress-of-packed-member] 550 | collect_langs(sp, s->wData); drivers/usb/gadget/composite.c:555:25: warning: taking address of packed member of ‘struct usb_string_descriptor’ may result in an unaligned pointer value [-Waddress-of-packed-member] 555 | collect_langs(sp, s->wData); Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
