The driver is missing the iio_buffer_attach() call. As such it will attempt to free the buffer twice on removal. Introduced in commit 9e69c9 ("iio: Add reference counting for buffers"). Signed-off-by:Lars-Peter Clausen <lars@metafoo.de> Reported-by:

the index argument to sign_extend32() gives the bit position (from 0) to the sign bit so e.g. if the measurement has 16-bit resolution, we need to pass 15; a measurement of 0x8000 should be reported as -32768, not 32768 Signed-off-by:

We can't store the trigger instance created by iio_trigger_alloc, in trig field of iio_device structure. This needs to be stored in the driver private data. Othewise it can result in crash during module unload. Hence created a trig_ptr in the common data structure for each HID sensor IIO driver and storing here. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

sig_cfg.clk_pol controls the 'di0_polarity_disp_clk' bit of register IPUx_DI0_GENERAL through the following code in imx-drm/ipu-v3/ipu-di.c: if (!sig->clk_pol) di_gen |= DI_GEN_POLARITY_DISP_CLK; 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 really white. Russell King initially reported this problem at: http://www.spinics.net/lists/arm-kernel/msg279805.html Inverting 'di0_polarity_disp_clk' leads to stable HDMI output image. Tested on the following boards: - mx6solowandboard (HDMI output) - mx6qwandboard (HDMI output) - mx6qsabrelite (LVDS) - mx6qsabresd (HDMI output and LVDS) - mx6dlsabresd (HDMI output) - mx53qsb (parallel WVGA display) Reported-by:

Replace the use of the `S626_MULT_X1`, `S626_MULT_X2` and `S626_MULT_X4` clock multiplier values with the equivalent `S626_CLKMULT_1X`, `S626_CLKMULT_2X` and `S626_CLKMULT_4X` values to avoid duplication. Replace the use of `S626_MULT_X0` with a new macro `S626_CLKMULT_SPECIAL` (this is treated specially by the 'ClkMultA'/'ClkMultB' field of the 'CRA'/'CRB' register).

The 'IndxSrc' value for the standardized encoder setup is currently 1 bit wide and takes one of the following values: S626_INDXSRC_HARD = 0 // index source from hardware encoder S626_INDXSRC_SOFT = 1 // index source software controlled by IndxPol However the hardware 'IndxSrcA' and 'IndxSrcB' values for the 'A' and 'B' counters are 2 bits wide. The above standardized values 0 and 1 correspond to the hardware values 0 and 2. In order to simplify conversions between the standardized values and hardware values, expand the range of standardized values to cover all four possible values. The new values are as follows: S626_INDXSRC_ENCODER = 0 // index source from hardware encoder S626_INDXSRC_DIGIN = 1 // index source from digital inputs S626_INDXSRC_SOFT = 2 // index source s/w controlled by IndxPol S626_INDXSRC_DISABLED = 2 // index source disabled (Note the change in value for `S626_INDXSRC_SOFT` and the replacement of `S626_INDXSRC_HARD` with `S626_INDXSRC_ENCODER` for consistency with the `CntSrc` values.)

Use the new macros defined in "s626.h" for constructing and decomposing 'CRA', 'CRB' and standardized encoder setup values to make the conversions between standardized encoder setup values, and CRA/CRB register values easier to follow. There is some messing about with the 'IndxSrc' values which are 1-bit wide in the standardized encoder setup, and 2-bit wide in the 'CRA' and 'CRB' register values. This will be addressed by a later patch. Signed-off-by:
