Subject: [PATCH 5.10 096/243] usb: gadget: f_hid: fix endianness issue with descriptors
From: Ruslan Bilovol <ruslan.bilovol@...il.com>
[ Upstream commit 33cb46c4676d01956811b68a29157ea969a5df70 ]
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.
