In `@cpp/tensorrt_llm/thop/causalConv1dOp.cpp`:
- Line 267: The TORCH_CHECK invocation validating conv_state_indices' scalar
type is missing a terminating semicolon causing a compile error; locate the line
containing TORCH_CHECK(conv_state_indices.scalar_type() == torch::kInt32) and
add a semicolon at the end of that statement so it reads as a complete statement
(ensure no other tokens are accidentally altered around the TORCH_CHECK or
conv_state_indices reference).

In `@tensorrt_llm/_torch/modules/fla/fused_sigmoid_gating_recurrent.py`:
- Around line 204-206: The else branch for when initial_state_source is None
sets s_h0_0 but fails to define slot_num, causing a NameError later when
constructing h0_dim0; update the else branch in the
fused_sigmoid_gating_recurrent logic to also initialize slot_num (e.g., set
slot_num = 0 or the appropriate default) whenever initial_state_source is None
so downstream use in h0_dim0 and any other uses of slot_num is valid; locate the
block around s_h0_0 and initial_state_source in
fused_sigmoid_gating_recurrent.py to make this change.

In `@tensorrt_llm/_torch/modules/fla/utils.py`:
- Around line 179-181: The positional-argument exclusion is broken because the
generator at contiguous_args compares tensor objects to strings (i in
exclude_args) instead of checking parameter names; update the logic in the
contiguous_args generator (and its surrounding function) to map positional
indices to parameter names using inspect.signature (or similar) and check the
parameter name against exclude_args before calling .contiguous(); i.e.,
determine each positional arg's parameter name from the function signature, and
only call i.contiguous() when the parameter name is not in exclude_args (leave
keyword exclusion using kwargs as-is).
