staging: comedi: pcl818: Fix endian problem for AI command data

commit 148e34fd33d53740642db523724226de14ee5281 upstream. The analog input subdevice supports Comedi asynchronous commands that use Comedi's 16-bit sample format. However, the call to `comedi_buf_write_samples()` is passing the address of a 32-bit integer parameter. On bigendian machines, this will copy 2 bytes from the wrong end of the 32-bit value. Fix it by changing the type of the parameter holding the sample value to `unsigned short`. [Note: the bug was introduced in commit edf4537bcbf5 ("staging: comedi: pcl818: use comedi_buf_write_samples()") but the patch applies better to commit d615416de615 ("staging: comedi: pcl818: introduce pcl818_ai_write_sample()").] Fixes: d615416de615 ("staging: comedi: pcl818: introduce pcl818_ai_write_sample()") Cc: # 4.0+ Signed-off-by: Ian Abbott Link: https://lore.kernel.org/r/20210223143055.257402-10-abbotti@mev.co.uk Signed-off-by: Greg Kroah-Hartman

commit b2e78630f733a76508b53ba680528ca39c890e82 upstream. The analog input subdevice supports Comedi asynchronous commands that use Comedi's 16-bit sample format.

Fix it by changing the type of the variables holding the sample value to `unsigned short`. The type of the `val` parameter of `pci1710_ai_read_sample()` is changed to `unsigned short *` accordingly. The type of the `val` variable in `pci1710_ai_insn_read()` is also changed to `unsigned short` since its address is passed to `pci1710_ai_read_sample()`.

staging: comedi: addi_apci_1500: Fix endian problem for command sample

2021-03-17T16:03:54+00:00

commit ac0bbf55ed3be75fde1f8907e91ecd2fd589bde3 upstream. The digital input subdevice supports Comedi asynchronous commands that read interrupt status information. This uses 16-bit Comedi samples (of which only the bottom 8 bits contain status information). However, the interrupt handler is calling `comedi_buf_write_samples()` with the address of a 32-bit variable `unsigned int status`. On a bigendian machine, this will copy 2 bytes from the wrong end of the variable. Fix it by changing the type of the variable to `unsigned short`.
