Subject: HID: Reorder fields in 'struct hid_input'
X-Git-Tag: v6.6-rc1~96^2~14
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=574d06ceb88fb735a7d88c22e6531f4849aada51;p=thirdparty%2Fkernel%2Flinux.git

HID: Reorder fields in 'struct hid_input'

Group some variables based on their sizes to reduce hole and avoid padding.
On x86_64, this shrinks the size of 'struct hid_input'
from 72 to 64 bytes.

It saves a few bytes of memory and is more cache-line friendly.
