Subject: [PATCH] usb: gadget: f_hid: fix endianness issue with descriptors
Git-commit: 33cb46c4676d01956811b68a29157ea969a5df70
Patch-mainline: v5.14-rc1
References: git-fixes
Running sparse checker it shows warning message about
incorrect endianness used for descriptor initialization:
| f_hid.c:91:43: warning: incorrect type in initializer (different base types)
| f_hid.c:91:43: expected restricted __le16 [usertype] bcdHID
| f_hid.c:91:43: got int
Fixing issue with cpu_to_le16() macro, however this is not a real issue
as the value is the same both endians.
