The file ft1000_hw.c is still full of coding style problems that make it
challenging to read and understand. The lines inside the switch cases
in ft1000_proc_drvmsg() are indented too deeply, so remove one leading
tab. Join lines that are now able to fit in the 80 character limit.
This will take care of the "too many leading tabs" issue. Run
checkpatch.pl on the file, and correct all other issues it reports
(except lines with user visible strings over 80 chars).

The function dsp_broadcast_msg_id() has four levels of nesting. Move the
handling for failed allocation for *dpram_blk from the else block at the
end to the block immediately following the test, reverse the sense of the

The newly extracted function handle_misc_portid still has several
unnecessary levels of nesting, having inherited its logic from the
original extracted lines. Move handling for failed memory allocation
(of *pdpram_blk) to the top of the function, and return -1 from within
it. This eliminates the if statement around the body of the function.
Change two levels of nested if/else to an if/else-if/else. Create a
label, exit_failure, at the end of the function with the cleanup code,
and goto it at all points of failure. Also, goto it if the call to
ft1000_receive_cmd() fails, instead of descending into an if block if
it succeeds. Pull all lines from inside the former if blocks to the
left, and rejoin lines to take advantage of reclaimed horizontal space.

The ft1000 driver ignores the normal Linux error codes, using its
own macros, STATUS, STATUS_SUCCESS, and STATUS_FAILURE, instead.
Unsigned variables (u16 and u32) are sometimes used to hold them.
This patch converts all occurences of these macros to 0, 0 and -1,
respectively. It also changes the last remaining status variables
(mostly called status and ret) to ints, and removes the declarations
of the macros. This patch does not correct the whitespace issues
in the lines where the changes were made.

The file ft1000_hw.c contains formal C99 style function headers that
waste space and convey little to no useful information. This patch
converts the headers to either one line standard /* */ style comments
or shorter standard style headers with parameter lists (if the parameter
list seemed helpful), or eliminates them entirely. Besides needing to be
made of its own accord, this change is in preparation to eliminate the
nonstandard STATUS_* #defines from the driver since they were cited in most
of the headers.

Two files in the ft1000 usb driver ignore expected Linux error codes,
and instead use two STATUS_SUCCESS 0, and STATUS_FAILURE
0x1001. This patch removes all remaining occurrences of these from the
file ft1000_download.c. All occurrences of STATUS_SUCCESS have been
replaced by 0, and occurrences of STATUS_FAILURE have been replaced by
-1. One occurence of STATUS_FAILURE has been completely removed:
get_handshake collects either a local #define or 0 from its helper
function, check_usb_db, and immediately sets the collecting variable to
STATUS_FAILURE if the #define is returned. check_usb_db has been
modified to return -1 instead of the #define.

This patch fixes the bug in reset_store caused by accessing NULL pointer.

The bdev gets its value from bdget_disk() which could fail when memory
pressure is severe and hence can return NULL because allocation of
inode in bdget could fail.

Hence, this patch introduces a check for bdev to prevent reference to a
NULL pointer in the later part of the code. It also removes unnecessary
check of bdev for fsync_bdev().

The ft1000 usb driver ignores expected Linux error codes, and uses two
values defined in ft1000_usb.h: STATUS_SUCCESS 0, and STATUS_FAILURE
0x1001; and sometimes -1. This patch changes the return values of the
function scram_start_dwnld to match the status of the handshake returned
by its helper functions, get_handshake and get_handshake_usb. If the
handshake fails, -ENETRESET is returned instead of the inappropriate
STATUS_FAILURE. Also, a new test has been added to differentiate failure
due to timeout from failure due to net reset (the default). -ETIMEDOUT
is returned in this case. Finally, 0 is returned on success instead of
STATUS_SUCCESS.

The ft1000 usb driver ignores expected Linux error codes, and uses two
values defined in ft1000_usb.h: STATUS_SUCCESS 0, and STATUS_FAILURE
0x1001; and sometimes -1. This patch changes the return value of the
function write_dpram_32_and check to 0 or -EREMOTEIO, respectively. The
relevant change was made in the helper function check_buffers (which is
only called from write_dpram32_and_check); it now returns 0 on success
and -EREMOTEIO on failure, and this is allowed to propagate through
write_dpram32_and_check. Assignments to the return variable status that
are no longer needed were removed as well. In one function up the call
chain, dsp_reload in ft1000_hw.c, the status variable was changed from
u16 to int to avoid collecting a signed value in an unsigned variable.

IPUx_DI0_GENERAL through the following code in imx-drm/ipu-v3/ipu-di.c:

	if (!sig->clk_pol)

With 'di0_polarity_disp_clk' bit set we do not have stable HDMI output on
mx6solo: contours of pictures look jittery and the white colour does not appear

Russell King initially reported this problem at:
