c975f9dd10 staging: wilc1000: change data type of wid argument in wilc_wlan_cfg_get_val
This patch changes data type of wid argument in wilc_wlan_cfg_get_val
from u32 to u16. It is better to change data type of wid because wid has
one of enum WID_T that is data type of u16. And, there is no need to use
u16 type casting when calling wilc_wlan_cfg_get_wid_value function.

304d13ff4d staging: lustre: libcfs: replace direct HZ access with kernel APIs
On some customers' systems, the kernel was compiled with HZ defined
to 100, instead of 1000. This improves performance for HPC applications.
However, to use these systems with Lustre, customers have to re-build
Lustre for the kernel because Lustre directly uses the defined constant
HZ.

Since kernel 2.6.21, some non-HZ dependent timing APIs become non-
inline functions, which can be used in Lustre codes to replace the
direct HZ access.

These kernel APIs include:
  jiffies_to_msecs()
  jiffies_to_usecs()
  jiffies_to_timespec()
  msecs_to_jiffies()
  usecs_to_jiffies()
  timespec_to_jiffies()

 And here are some samples of the replacement:
  HZ            -> msecs_to_jiffies(MSEC_PER_SEC)
  n * HZ        -> msecs_to_jiffies(n * MSEC_PER_SEC)
  HZ / n        -> msecs_to_jiffies(MSEC_PER_SEC / n)
  n / HZ        -> jiffies_to_msecs(n) / MSEC_PER_SEC
  n / HZ * 1000 -> jiffies_to_msecs(n)

This patch replaces the direct HZ access in the libcfs module.

c11e27a4ee staging: lustre: libcfs: bug fixes for cfs_crypto_hash_final()
Change cfs_crypto_hash_final() to always clean up the hash descrptor
instead of not doing this in error cases.  All of the callers were
just calling cfs_crypto_hash_final() immediately to clean up the
descriptor anyway, and the old behaviour is unlike other init/fini
functions, and prone to memory leaks and other incorrect usage.  The
callers can call cfs_crypto_digest_size() to determine the hash size
in advance if needed, and avoid complexity in cfs_crypto_hash_final().

b42ca86ad6 staging: comedi: ni_tio: remove BUG() checks for ni_tio_get_clock_src()
This function calls some helper functions to convert the counter variant
specific clock select bits into the generic enum ni_gpct_clock_source_bits
equivelent. These helper functions currently BUG() if the clock select
bits are invalid.

It then calls ni_tio_clock_period_ps() to figure out the clock period
based on the generic clock source. This function could also BUG() if
the prescale bits are invalid.

In reality this should never happen but refactor the code to return
-EINVAL instead and remove the BUG() checks.

These functions are also called by ni_tio_set_sync_mode(). When this
function is called by ni_tio_set_clock_src() the counter select bits
have already been validated.

592ef9fb8d staging: comedi: ni_tio: fix ni_tio_insn_config()
The (*insn_config) functions are supposed to return an errno or the number
of 'data' values used for the instruction (insn->n). Currently this function
returns an errno or 0. Fix the function to work like the core expects.
