On a few places, := were using instead of +=, causing drivers to
not compile.

While here, standardize the usage of += on all cases where multiple
lines are needed, and for obj-y/obj-m targets, and := when just one
line is needed, on <module>-obj rules.

In JPEG mode, the size of image is variable due to different JPEG compression
rate. We only can get the pix->sizeimage from the user.

If we clear pix->sizeimage in soc_camera_try_fmt() then we will get it from:
	ret = soc_mbus_image_size(xlate->host_fmt, pix->bytesperline,
				pix->height);
	if (ret < 0)
		return ret;

	pix->sizeimage = max_t(u32, pix->sizeimage, ret);

In general, this sizeimage will be larger than the actul JPEG image size.

But vb2 will check the buffer and size of image in __qbuf_userptr():
	/* Check if the provided plane buffer is large enough */
	if (planes[plane].length < q->plane_sizes[plane])

So we shouldn't clear the pix->sizeimage and also shouldn't re-calculate
the pix->sizeimage in soc_mbus_image_size() in JPEG mode

We also shouldn't re-calculate pix->bytesperline:
	ret = soc_mbus_bytes_per_line(pix->width, xlate->host_fmt);
	if (ret < 0)
		return ret;

	pix->bytesperline = max_t(u32, pix->bytesperline, ret);

pix->bytesperline also should be set by the user or by the driver's
try_fmt() implementation.

This patch checks the state of the buffer when calling .buf_init() method.
This is needed for the USERPTR buffer type, because in that case
.buf_init() is called every time a buffer is queued, and not only once
during the preparation stage, like in the MMAP case. Without this check
buffers get initialised repeatedly, which also leads to the allocation
of new DMA descriptors, of which there is only a final relatively small
number available. Both MMAP and USERPTR methods were successfully tested.

Using devm_kzalloc simplifies the code and ensures that the use of
devm_request_irq is safe.  When kzalloc and kfree were used, the interrupt
could be triggered after the handler's data argument had been freed.

This also introduces some missing initializations of the return variable
ret, and uses devm_request_and_ioremap instead of the combination of
devm_request_mem_region and devm_ioremap.

The problem of a free after a devm_request_irq was found using the
following semantic match (http://coccinelle.lip6.fr/)

// <smpl>
@r exists@
expression e1,e2,x,a,b,c,d;
