HID: intel-ish-hid: avoid bogus uninitialized-variable warning
Older compilers like gcc-4.8 don't see that the variable is
initialized when it is used:
In file included from include/linux/compiler_types.h:68:0,
from <command-line>:0:
drivers/hid/intel-ish-hid/ishtp-fw-loader.c: In function 'load_fw_from_host':
include/linux/compiler-gcc.h:75:45: warning: 'fw_info.ldr_capability.max_dma_buf_size' may be used uninitialized in this function [-Wmaybe-uninitialized]
#define __UNIQUE_ID(prefix) __PASTE(__PASTE(__UNIQUE_ID_, prefix), __COUNTER__)
^
drivers/hid/intel-ish-hid/ishtp-fw-loader.c:770:22: note: 'fw_info.ldr_capability.max_dma_buf_size' was declared here
struct shim_fw_info fw_info;
^
Make sure to initialize it before returning an error from ish_query_loader_prop().
