From: Hannes Reinecke Date: Tue, 15 Aug 2017 06:58:04 +0000 (+0200) Subject: scsi: hpsa: add support for legacy boards X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=135ae6edeb51979d0998daf1357f149a7d6ebb08;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git scsi: hpsa: add support for legacy boards Add support for legacy boards, ensuring to enable the driver for those boards only when 'hpsa_allow_any' is set. The attribute 'legacy_board' is set to '1' if the device is a legacy board, and '0' otherwise. Signed-off-by: Hannes Reinecke Acked-by: Don Brace Signed-off-by: Martin K.
