linux: bump RK3326 kernel 6.12.79 -> 6.12.94 (LTS)

Sliding within the same 6.12 LTS branch (longterm support runs until
December 2026), this picks up 15 stable patch releases of bugfix
and CVE work without touching ABI/API.

Pin the source tarball with PKG_SHA256 so a network MITM cannot
silently swap the kernel under us.

Drop 0020-usb-gadget-u_ether-guard-NULL-gadget-in-eth_get_drvinfo.patch
— that fix landed upstream in 6.12.81 stable. Keeping our copy would
conflict on apply.

The remaining nine patches all touch areas (panfrost, ntsync,
rtl8xxxu) that received no churn in the 79..94 window, so they
should apply unchanged; the next docker-RK3326 build will confirm.

Subject: [PATCH] usb: gadget: u_ether: Fix NULL pointer deref in eth_get_drvinfo
Commit ec35c1969650 ("usb: gadget: f_ncm: Fix net_device lifecycle with
device_move") reparents the gadget device to /sys/devices/virtual during
unbind, clearing the gadget pointer. If the userspace tool queries on
the surviving interface during this detached window, this leads to a
NULL pointer dereference.
Unable to handle kernel NULL pointer dereference
Call trace:
eth_get_drvinfo+0x50/0x90
ethtool_get_drvinfo+0x5c/0x1f0
__dev_ethtool+0xaec/0x1fe0
dev_ethtool+0x134/0x2e0
dev_ioctl+0x338/0x560
Add a NULL check for dev->gadget in eth_get_drvinfo(). When detached,
skip copying the fw_version and bus_info strings, which is natively
handled by ethtool_get_drvinfo for empty strings.
