%description
A Linux kernel module for Thrustmaster T300RS, T248, and experimental support
for TX, T128, T598, TS-PC and TS-XW racing wheels.

This akmod package automatically builds kernel modules for each installed kernel
version, ensuring the driver works after kernel updates without manual rebuilding.

The driver includes wheel initialization modules (hid-tminit) and the main
force feedback driver (hid-tmff-new).

%prep
# Extract main source
%autosetup -n %{kmod_name}-%{version}

# Extract hid-tminit submodule (Source1)
mkdir -p deps
tar -xzf %{SOURCE1} -C deps

# Verify submodule is in place
if [ ! -f deps/hid-tminit/Makefile ]; then
    echo "ERROR: hid-tminit submodule not found after extraction"
    exit 1
