Arnd Bergmann f5a430c8ee Input: cyapa_gen6 - fix out-of-bounds stack access
commit f051ae4f6c732c231046945b36234e977f8467c6 upstream.

gcc -Warray-bounds warns about a serious bug in
cyapa_pip_retrieve_data_structure:

drivers/input/mouse/cyapa_gen6.c: In function 'cyapa_pip_retrieve_data_structure.constprop':
include/linux/unaligned/access_ok.h:40:17: warning: array subscript -1 is outside array bounds of 'struct retrieve_data_struct_cmd[1]' [-Warray-bounds]
   40 |  *((__le16 *)p) = cpu_to_le16(val);
drivers/input/mouse/cyapa_gen6.c:569:13: note: while referencing 'cmd'
  569 |  } __packed cmd;
      |             ^~~

Apparently the '-2' was added to the pointer instead of the value,
writing garbage into the stack next to this variable.

Fixes: c2c06c41f7 ("Input: cyapa - add gen6 device module support")
