Thanks for posting this driver. One request for the future: please split this
patch up in smaller pieces: one for each c source for example. That makes it

Yes, the MMU version of remap_pfn_range() does permit non-page-aligned

Since b9bf2eafaad9c1ef02fb3db38c74568be601a43a, the function
ds3000_firmware_ondemand() is called only once during init. This
locking scheme may have been useful when the firmware was loaded at
each tune.
Furthermore, it looks like this 'lock' was put in to prevent concurrent
access (and not
- if kmalloc() returns NULL, we can return immediately without trying
to kfree() a NULL pointer.
- if i2c_transfer() fails, error out immediately instead of trying to
upload the remaining bytes of the firmware.
- the error code is then properly propagated down to ds3000_initfe().

ds3000_readreg() returns negative values in case of i2c failures. The

Hi all,
This is the full patch series containing API fixes as discussed during the

Regarding the 'make ioctl const' patches: I've only done the easy ones in
this patch series. The remaining write-only ioctls are used much more widely,
so changing those will happen later.
