Subject: [PATCH v2 1/5] HID: core: Move internal declarations and drop unused exports
Date: Fri, 16 Oct 2026 15:41:48 -0700 [thread overview]
Message-ID: <20261016-test-hidraw-base-v2-1-153f67a20cad@gmail.com> (raw)
In-Reply-To: <20261016-test-hidraw-base-v2-0-153f67a20cad@gmail.com>
Several declarations in the public HID header and exported symbols are
used solely within the core HID module (linked together from hid-core,
hid-input, and hid-quirks into hid.o).
Move internal request, input hook, resolution multiplier, and device
matching declarations into a private header shared across core HID
sources, and drop the unused GPL symbol exports.
