Fixup.

Style changes cem@ and unsigned integer constants.

It's probably also worth pointing out that because a lot of things in USB are generally named in Hungarian notation, some concessions already get made to that in/around dev/usb/*.

I actually find spelling out the bits in hex is more useful here - it's a driver and it's accessing a register, so although UINT32_MAX might well represent the value (and be equivalent to it), stylistically spelling out those bits makes it crystal clear that we're acting on a register.

Catch up with Sec. 7.6.9 of xHCI v1.1: DbC context sizes (DbC Info and Endpoint) are always 64 bytes, regardless of whether or not the host controller uses 32 byte contexts for ordinary endpoints (HCCPARAMS1).

Simplify based on feedback. MSI detected and used OK.

Please consider renaming to RB_COUNT(), and please do not change the memory layout or semantics of basic containers which are already used in-kernel (discussed on src-committers@)

The new behaviour appears to be POSIXly correct. POSIX shutdown spec
