Subject: possible bug in linux-6.2/drivers/spi/spi-sn-f-ospi.c

Hello there,

Static analyser cppcheck says:

linux-6.2/drivers/spi/spi-sn-f-ospi.c:614:31: style: Same expression 'SPI_TX_OCTAL' found multiple times in chain of '|' operators. [duplicateExpression]

Source code is

ctlr->mode_bits = SPI_TX_DUAL | SPI_TX_QUAD | SPI_TX_OCTAL
| SPI_RX_DUAL | SPI_RX_QUAD | SPI_TX_OCTAL
| SPI_MODE_0 | SPI_MODE_1 | SPI_LSB_FIRST;

Maybe better code:

ctlr->mode_bits = SPI_TX_DUAL | SPI_TX_QUAD | SPI_TX_OCTAL
| SPI_RX_DUAL | SPI_RX_QUAD | SPI_RX_OCTAL
| SPI_MODE_0 | SPI_MODE_1 | SPI_LSB_FIRST;

Regards
