Calling optee_disable_shm_cache() in both if and else. It could be
put in front of if().
Ideally, I could just use optee_remove for shutdown() too.
But it would not look good. Hence this approach.
What is the problem with using optee_remove() for shutdown()?
There is no problem, I just thought it would be more cleaner/readable
with this approach. If you'd like to keep it simple by just calling
optee_remove() for shutdown() too, I could quickly send out V2.
In the patch you posted it looks like you'd like to call
only optee_disable_shm_cache() in the case of shutdown. Like:
static void optee_shutdown(struct platform_device *pdev)
{
optee_disable_shm_cache(platform_get_drvdata(pdev));
}
and optee_remove() kept as it was before this patch.
Sure, Will have it fixed and send out V2.
Thanks.

[RFC] PCI: allow sysfs file owner to read the config space with CAP_SYS_RAWIO
From: Allen Pais Access to pci config space is explictly checked with CAP_SYS_ADMIN in order to read configuration space past the frist 64B. Since the path is only for reading, could we use CAP_SYS_RAWIO? This patch contains a simpler fix, I would love to hear from the Maintainers on the approach. The other approach that I considered was to introduce and API which would check for multiple capabilities, something similar to perfmon_capable()/bpf_capable(). But I could not find more users for the API and hence dropped it. The problem I am trying to solve is to avoid handing out CAP_SYS_ADMIN for extended reads of the PCI config space.

[PATCH] linux/kernel.h: add container_from()
Introduce container_from() as a generic helper instead of
sub-systems defining a private from_* API
(Eg: from_tasklets recently introduced in
12cc923f1ccc: Tasklet: Introduce new initialization API)
The helper is similar to container_of() in argument order
with the difference of naming the containing structure instead
of having to specify its type.

[PATCH 05/16] wireless: atmel: convert tasklets to use new tasklet_setup() API
From: Allen Pais
In preparation for unconditionally passing the
struct tasklet_struct pointer to all tasklet
callbacks, switch to using the new tasklet_setup()
and from_tasklet() to pass the tasklet pointer explicitly
and remove .data field.

[PATCH 3/9] net: cdc_ncm: convert tasklets to use new tasklet_setup() API
From: Allen Pais
In preparation for unconditionally passing the
struct tasklet_struct pointer to all tasklet
callbacks, switch to using the new tasklet_setup()
and from_tasklet() to pass the tasklet pointer explicitly.
