net: iosm: Prevent underflow in ipc_chnl_cfg_get()
The bounds check on "index" doesn't catch negative values. Using ARRAY_SIZE() directly is more readable and more robust because it prevents negative values for "index". Fortunately we only pass valid values to ipc_chnl_cfg_get() so this patch does not affect runtime. Reported-by:Solomon Ucko <solly.ucko@gmail.com> Signed-off-by:
