"""
bytes-per-pixel is stored in bits 5-7 of calculated mask.
But when calculating bytes-per-line we were extracting wrong value
instead of bytes-per-pixel, which was usually 2 times bigger -- e.g. for
PAL YUV 422 I was getting ((mask3 & 0x00F0) >> 4) = 4 bytes instead of 2.
The error here is that even in comments there is a line saying
* bytesperpixel IS ((0x00E0 & easycap_format.mask) >> 5)
but we were using
((0x00F0 & easycap_format.mask) >> 4)
With 2 times bigger bytesperpixel and automatically bytesperline, the
video was shown halfheight'ed, which is understandable if we look at
video-memory layout:
<------- bytesperline -------->
<- real bpl ->
x0----------y0 x1-----------y1
x2----------y2 x3-----------y3
xn----------yn xn-----------yn
<garbage>
for each line, we should display width pixels, then move to next line
with bytesperline, and oops, if bytesperline = 2*real-bytesperlin, we'll
skip one line and move to next-next line, and so only half lines will be
shown.
Initially I've debugged the problem with my video application[1], but
I've checked that after this patch both rawv (mine app) and tvtime work
correctly.
[1] http://repo.or.cz/w/rawv.git
P.S. why at all we use those mask/shifts? Why not use bitfields?

For instance, ZRAM_UNCOMPRESSED bit can be cleared by zram_free_page()
called from a concurrent write between the time ZRAM_UNCOMPRESSED has
been set and the time it is tested to unmap KM_USER0 in
zram_bvec_write(). This ultimately leads to kernel panic.
Also, a read request can occurs when the page has been freed by a
running write request and before it has been updated, leading to
zero filled block being incorrectly read and "Read before write"
error message.
This patch replace the current mutex by a rw_semaphore. It extends
the protection to zram table (currently, only compression buffers are
protected) and read requests (currently, only write requests are
protected).
