2020-07-23bus: fsl-mc: probe the allocatable objects firstGrigore Popescu1-17/+40
Because the DPNIs are probed before DPMCPs and other objects that need to be allocated, messages like "No more resources of type X left" are printed by the fsl-mc bus driver. This patch resolves the issue by probing the allocatable objects first and then any other object that may use them.

2020-07-23cardreader/rtsx_pcr.c: use generic power managementVaibhav Gupta1-22/+11
Drivers should not use legacy power management as they have to manage power states and related operations, for the device, themselves. This driver was handling them with the help of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device(), etc. With generic PM, all essentials will be handled by the PCI core. Driver needs to do only device-specific operations. The driver was also using pci_enable_wake(...,..., 0) to disable wake. Use device_wakeup_disable() instead. Compile-tested only.

2020-07-23mei: Avoid the use of one-element arraysGustavo A. R. Silva2-5/+5
One-element arrays are being deprecated[1]. Replace the one-element arrays with a simple value type u8 reserved, once this is just a placeholder for alignment. Also, while there, use the preferred form for passing a size of a struct. The alternative form where struct name is spelled out hurts readability and introduces an opportunity for a bug when the variable type is changed but the corresponding sizeof that is passed as argument is not.

2020-07-23mei: hdcp: Replace one-element array with flexible-array memberGustavo A. R. Silva2-2/+2
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Also, make use of the array_size() helper instead of the open-coded version in memcpy(). These sorts of multiplication factors need to be wrapped in array_size(). And while there, use the preferred form for passing a size of a struct. The alternative form where struct name is spelled out hurts readability and introduces an opportunity for a bug when the pointer variable type is changed but the corresponding sizeof that is passed as argument is not.
