wifi: rtlwifi: PCI related fixes & cleanups

expand
|
The rtlwifi driver has code fragments that are using old interface or custom code to access PCIe capabilities which is buggy and messy. First two patches are fixes to problems related to ASPM and LNKCTL register RMW operations. The rest of the patches cleanup PCIe capability related code. Additional note: This series provides only a stop-gap solution to the RMW concurrency issue, the overall plan is to migrate all ASPM related handling into the ASPM service driver in order for it to accurately track ASPM state [1].
