Hi Krzysztof,

Sorry, just back from Chinese New Year holiday.

This is also a generic problem.

Agree to simplify the commit message. How about the following subject and commit message?

Subject:  
Use device number to check RCiEPBitmap of RCEC

Commit message: 
rcec_assoc_rciep() used the combination of device number and function number 'devfn' to check whether the corresponding bit in the RCiEPBimap of RCEC was set. According to [1], it only needs to use the device number to check the corresponding bit in the RCiEPBitmap was set. So fix it by using PCI_SLOT() to convert 'devfn' to device number for rcec_assoc_rciep().
[1] PCIe r5.0, sec "7.9.10.2 Association Bitmap for RCiEPs"


Thanks!
