[PATCH v2 05/13] spi: cadence-qspi: Remove an useless operation
From: Miquel Raynal (Schneider Electric)
Date: Thu Jan 15 2026 - 04:25:44 EST
Right above writing the register value back based on 'div' value, there
is the following check:
if (div > CQSPI_REG_CONFIG_BAUD_MASK)
div = CQSPI_REG_CONFIG_BAUD_MASK;
which means div does not need to be AND'ed against the bitfield mask.
Remove this redundant operation.
