As noted back in March, the plan with Linux 6.4 is to start removing old, unused and unmaintained PCMCIA drivers. As part of that process to begin dropping old PCMCIA/CardBus driver code from the kernel, all of the PCMCIA "char" drivers were on the chopping block. Linus Torvalds pulled in the char/misc changes this week for Linux 6.4 and indeed those drivers are now removed. Meanwhile this pull introduced the new AMD CDX subsystem...

It's likely been years since many of you have heard of Firewire and some readers likely never had the opportunity to use it. The Firewire interface was great back in the day and during the early period of digital video cameras, but modern versions of USB and Thunderbolt are far faster, allow longer cable distances, and numerous other advantages. While Firewire hasn't seen much activity in years and can be outpaced by USB 3.0 and beyond, there is a new Firewire subsystem maintainer for the Linux kernel and he intends to keep at it for the next six years...
