#     ocxl: Fix access to the AFU Descriptor Data
#     
#     The AFU Information DVSEC capability is a means to extract common,
#     general information about all of the AFUs associated with a Function
#     independent of the specific functionality that each AFU provides.
#     Write in the AFU Index field allows to access to the descriptor data
#     for each AFU.
#     
#     With the current code, we are not able to access to these specific data
#     when the index >= 1 because we are writing to the wrong location.
#     All requests to the data of each AFU are pointing to those of the AFU 0,
#     which could have impacts when using a card with more than one AFU per
#     function.
#     
#     This patch fixes the access to the AFU Descriptor Data indexed by the
#     AFU Info Index field.
#     
#     Fixes: 5ef3166e8a32 ("ocxl: Driver code for 'generic' opencapi devices")
