General issue report

Hello,

I am facing issue using esp32c6 spi 2 as slave.
During debug process I was confusing with void spi_slave_hal_store_result(spi_slave_hal_context_t *hal), please look image below:

I am not using dma, so I am running line:
spi_ll_read_buffer(hal->hw, hal->rx_buffer, hal->bitlen);

Look, uint32_t bitlen; ///< Expected maximum length of the transaction, in bits. but the variable update in function is: hal->rcv_bitlen = spi_ll_slave_get_rcv_bitlen(hal->hw);

I think the right parameter for spi_ll_read_buffer is hal->rcv_bitlen, look:
