Subject: ide: don't display "BIOS" settings in ide_setup_dma()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8d9f9a76ea09911f4aaf0d9e852fd25335080f53;p=linux-beck.git

ide: don't display "BIOS" settings in ide_setup_dma()

Nowadays BIOS info is not very useful and only confuses users since:

- IDE always tries to use DMA

- BIOS info may not be accurate with modular IDE/libata
