From: Jasmin Jessich <jasmin@xxxxxx> These patch series implement a block read/write interface to the en50221 CAM control functions. The origin of this patches can be found in the Digital Devices Git on https://github.com/DigitalDevices/dddvb maintained by Ralph Metzler <rjkm@xxxxxxxxxxxxxx> The relevant changes concerning dvb-core/dvb_ca_en50221.c/.h and cxd2099/cxd2099.c/.h have been extracted from the mentioned repository by Daniel Scheller <d.scheller@xxxxxxx> and committed to his branch on https://github.com/herrnst/dddvb-linux-kernel/tree/mediatree/master-cxd2099 I split the patch set is smaller pieces for easier review, compiled each step, fixed code style issues in cxd2099/cxd2099.c/.h (checkpatch.pl) and tested the resulting driver on my hardware with the DD DuoFlex CI (single) card. Please note, that the block read/write functionality is already implemented in the currently existing cxd2099/cxd2099.c/.h driver, but deactivated. The existing code in this driver is also not functional and has been updated by the working implementation from the Digital Devices Git. Additionally to the block read/write functions, I merged also two patches in the en50221 CAM control state machine, which were existing in the Digital Devices Git. This are the first two patches of this series. There is another patch series coming soon "Fix coding style in en50221 CAM functions" which fixes nearly all the style issues in dvb-core/dvb_ca_en50221.c/.h, based on this patch series. So please be patient, if any of the dvb_ca_en50221.c/.h might be not 100% checkpatch.pl compliant. I tried to keep the original patch code from DD as much as possible. Apologizes if anything regarding the patch submission is/went wrong, as this is my first time contribution of a patch set.
