We need not be concerned about .remove functions and blocking the unbind sysfs operations, since that was already done in a recent commit. Lets remove any remaining modular references, so that when reading the drivers there is no doubt they are builtin-only. All drivers get mostly the same changes, so they are handled in batch. Changes are (1) convert to builtin_amba_driver, (2) delete module.h include where unused, and (3) relocate the description into the comments so we don't need MODULE_DESCRIPTION and associated tags. The etm3x and etm4x use module_param_named, and have been adjusted to just include moduleparam.h for that purpose. In commit f309d4443130bf814e991f836e919dca22df37ae ("platform_device: better support builtin boilerplate avoidance") we introduced the builtin_driver macro. Here we use that support and extend it to amba driver registration, so where a driver is clearly non-modular and builtin-only, we can update with the simple mapping of module_amba_driver(...) ---> builtin_amba_driver(...) Since module_amba_driver() uses the same init level priority as builtin_amba_driver() the init ordering remains unchanged with this commit.

And to make this a standalone commit that Mathieu can also add to his queue, I've squished the amba/bus.h change[2] into this change.] [1] http://www.spinics.net/lists/kernel/msg2096702.html [2] http://lkml.iu.edu/hypermail/linux/kernel/1510.1/02464.html drivers/hwtracing/coresight/coresight-etb10.c | 9 +++------ drivers/hwtracing/coresight/coresight-etm3x.c | 14 ++++++++------ drivers/hwtracing/coresight/coresight-etm4x.c | 4 +--- drivers/hwtracing/coresight/coresight-funnel.c | 9 +++------ drivers/hwtracing/coresight/coresight-replicator-qcom.c | 4 +--- drivers/hwtracing/coresight/coresight-replicator.c | 7 ++----- drivers/hwtracing/coresight/coresight-tmc.c | 9 +++------ drivers/hwtracing/coresight/coresight-tpiu.c | 9 +++------ drivers/hwtracing/coresight/coresight.c | 3 --- drivers/hwtracing/coresight/of_coresight.c | 1 - include/linux/amba/bus.h | 9 +++++++++ 11 files changed, 33 insertions(+), 45 deletions(-) diff --git a/drivers/hwtracing/coresight/coresight-etb10.c b/drivers/hwtracing/coresight/coresight-etb10.c index 92969dae739d..21f6afd24a66 100644 --- a/drivers/hwtracing/coresight/coresight-etb10.c +++ b/drivers/hwtracing/coresight/coresight-etb10.c @@ -1,5 +1,7 @@ /* Copyright (c) 2011-2012, The Linux Foundation.
