SCSI: sd: Reduce buffer size for vpd request
commit af73623f5f10eb3832c87a169b28f7df040a875b upstream. Somehow older areca firmware versions have issues with scsi_get_vpd_page() and a large buffer, the firmware seems to crash and the scsi error-handler will start endless recovery retries. Limiting the buf-size to 64-bytes fixes this issue with older firmware versions (<1.49 for my controller). Fixes a regression with areca controllers and older firmware versions introduced by commit: 66c28f97120e8a621afd5aa7a31c4b85c547d33d Reported-by: Nix <nix@esperi.org.uk> Tested-by: Nix <nix@esperi.org.uk> Signed-off-by: Bernd Schubert <bernd.schubert@itwm.fraunhofer.de> Acked-by: Martin K.
