Subject: [PATCH v2 0/6] VFIO platform reset module rework
This series fixes the current implementation by getting rid of the
usage of __symbol_get which caused a compilation issue with
CONFIG_MODULES disabled. On top of this, the usage of MODULE_ALIAS makes
possible to add a new reset module without being obliged to update the
framework. The new implementation relies on the reset module registering
its reset function to the vfio-platform driver.
The series is available at
https://git.linaro.org/people/eric.auger/linux.git/shortlog/refs/heads/v4.3-rc6-rework-v2
Best Regards
Eric
v1 -> v2:
* in vfio_platform_common.c:
- move reset lookup at load time and put reset at release: this is to
prevent a race between the 2 load module loads
- reset_list becomes static
- vfio_platform_register/unregister_reset take a const char * as compat
- fix node link
- remove old combo struct and cleanup proto of vfio_platform_get_reset
- add mutex to protect the reset list
* in calxeda xgmac reset module
- introduce vfio_platform_reset_private.h
- use module_vfio_reset_handler macro
- do not export vfio_platform_calxedaxgmac_reset symbol anymore
- add a pr_info to show the device is reset by vfio reset module
