lib/crc: remove unnecessary prompt for CONFIG_CRC_CCITT

ebiggers · ebiggers · commit 7939da264bcc · 2025-04-04T11:31:42.000-07:00
All modules that need CONFIG_CRC_CCITT already select it, so there is no need to bother users about the option. Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: "Martin K.
