^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) * Any SDIO/SDmem/MMC device plugged into the VUB300 will appear,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) * by virtue of this driver, to have been plugged into a local
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) * SDIO host controller, similar to, say, a PCI Ricoh controller
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) * This is because this kernel device driver is both a USB 2.0
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) * client device driver AND an MMC host controller driver. Thus
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) * if there is an existing driver for the inserted SDIO/SDmem/MMC
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) * device then that driver will be used by the kernel to manage
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) * the device in exactly the same fashion as if it had been
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) * directly plugged into, say, a local pci bus Ricoh controller

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) * RANT: this driver was written using a display 128x48 - converting it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) * to a line width of 80 makes it very difficult to support. In
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) * particular functions have been broken down into sub functions
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) * and the original meaningful names have been shortened into
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) * cryptic ones.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) * The problem is that executing a fragment of code subject to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) * two conditions means an indentation of 24, thus leaving only
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) * 56 characters for a C statement. And that is quite ridiculous!
