You can abbreviate the commit id:
Fixes commit eae79b4f3e82 ("rsi: fix memory leak in
rsi_load_ta_instructions()") which stopped the driver from functioning.

Add this before Signed-off-by line:
Fixes: eae79b4f3e82 ("rsi: fix memory leak in rsi_load_ta_instructions()")

Also no need to send email to stable@vger.kernel.org list, this line is
enough and the stable team will pick the commit automatically.
