Memory for zram->disk object may have already been freed after returning from destroy_device(zram), then it's unsafe for zram_reset_device(zram) to access zram->disk again. We can't solve this bug by flipping the order of destroy_device(zram) and zram_reset_device(zram), that will cause deadlock issues to the zram sysfs handler. So fix it by holding an extra reference to zram->disk before calling destroy_device(zram). Signed-off-by:

For aesthetic reasons, rename the function. Use a local variable for the 'reg' offset that is stored in the comedi_subdevice 'private' pointer to minimize the number of casts. Signed-off-by:

For aesthetic reasons, rename the function. Use a local variable for the 'reg' offset that is stored in the comedi_subdevice 'private' pointer to minimize the number of casts. Also, add local variables for the 'mask' and 'bits'. The outputs only need to be updated if the 'mask' indicates that the 'bits' are changing. Move the update code into the main 'if (mask)' block.

Convert the boardinfo declaration to C99 format and move it near the struct definition. Since the *_SIZE defines are only used in the boardinfo, remove them and just open code the values in the boardinfo. Signed-off-by:

According to the PCM-A/D-12/16 Operations Manual: NOTE: On the PCM-A/D-12 the lower nibble of the hex value will always be 0. Fix the pcmad_ai_insn_read() function to properly handle this by shifting the data after it has been read. Signed-off-by:

The comedi_config utility is used to attach to this board. One of the configuration options passed by the user sets the analog input encoding for straight binary or two's complement data. The hardware produces straight binary data when jumpered for 5V unipolar inputs and two's complement data when jumpered for +-10V bipolar inputs. Use the configuration option to correctly set the comedi_subdevice range_table. We can then use a helper function to determine what the range is when reading the analog inputs. This allows removing the 'twos_comp' variable from the private data (which was actually never used). Since the private data is now empty, remove it completely. Signed-off-by:

The comedi_config utility is used to attach to this board. One of the configuration options passed by the user sets the analog input reference for single-ended or differential inputs. Use the configuration option to correctly set the comedi_subdevice flags as well as the number of channels. Remove the 'differential' variable from the private data. Its not used by the driver.

Remove the comment before the function, the options are documented at the beginning of the file. Remove the PCMAD_SIZE define. It's only used in the attach to specify the io region size. For aesthetic reasons, add some whitespace to the subdevice init and reorder them a bit. Signed-off-by:

Use a local variable to read and munge the analog input data instead of directly using the 'data' pointer passed to the function. (*insn_read) functions either return an errno or the number of data values read. Change the final return to insn->n to make this clearer. Tidy up the function. Signed-off-by:

read_nic_*() functions are defined in r8192U_core.c. They call internally usb_control_msg() to read the nic registers and return the value read. Following a remark made by Dan Carpenter, if usb_control_msg() fails, the value returned will be invalid. To accommodate for this, this patch changes the functions to take a pointer as argument to set the value read and return 0 on success and the error status on failure, so that callers of read_nic_*() can check the return status. Some other fixes introduced in read_nic_*() functions are: The expressions (1<<EPROM_*_SHIFT) used to address and set the individual bits of the eeprom register were replaced with EPROM_*_BIT bitmasks to make the code more intuitive. EPROM_*_BIT bitmasks were defined in r8192U_hw.h and EPROM_*_SHIFT were removed. In netdev_err(), which is called in case of failure, the hardcoded function name in the error log message was replaced with __func__ to reduce line size. Also, from the error log message, it was omitted the word "Timeout" and it is just reported the error code since the failure can not only be due to timeout expiration but also due to a memory allocation failure. In case of timeout expiration, usb_start_wait_urb() prints an appropriate log message when debug is enabled. Finally, some minor fixes to the coding style were applied in lines affected by the above changes, including the removal of ifdef DEBUG_RX (the debugging of reads and writes of the nic registers shall be done with explicit check on their return status which will be added in a follow on patch).

Sean MacLennan fixed this in the rtl8192e driver and we should fix it here as well. It's pretty harmless. This information comes from the firmware, if we were to hit this bug we would read beyond the end of the array once or twice before returning and update our statistics with bogus data. Signed-off-by:

We don't need to implement crc32 and crc32pclmul on our own. The crc32-pclmul support was merged into the 3.8 kernel in commit 78c37d19, no need to keep a local copy in Lustre anymore. The crc32 implementation is identical to crypto-crc32. So drop Lustre's private implementation and select kernel crypto in Kconfig. Reported-by:

This patch replaces macro rx_hal_is_cck_rate() with the static inline function rx_hal_is_cck_rate(). This replacement was suggested by Dan Carpenter and has the following benefits: - improves code readability - guarantees type safety - improves code efficiency by enforcing the evaluation of the simple boolean expression (!pdrvinfo->RxHT) to be done before the evaluation of the more complex one (pdrvinfo->RxRate == DESC90_RATE1M || pdrvinfo->RxRate == DESC90_RATE2M || pdrvinfo->RxRate == DESC90_RATE5_5M || pdrvinfo->RxRate == DESC90_RATE11M) Signed-off-by:
