[PATCH v2 1/1] spi: Group cs_change and cs_off flags together in struct spi_transfer

From: Andy Shevchenko
Date: Thu Sep 08 2022 - 09:09:12 EST


The commit 5e0531f6b90a ("spi: Add capability to perform some transfer
with chipselect off") added a new flag but squeezed it into a wrong
group of struct spi_transfer members (note that SPI_NBITS_* are macros
for easier interpretation of the tx_nbits and rx_nbits bitfields).

Group cs_change and cs_off flags together and their doc strings.

v2: fixed some grammar issues, grouped doc strings as well
