Code is correct, i needs to be moved back by 2 to correct for the last
iteration of the while loop, since READ_NEXT_PAIR advances two. Fixing
the misleading indentation.

Fix a smatch warning:
drivers/staging/rtl8188eu/hal/rf_cfg.c:217
rtl88e_phy_config_rf_with_headerfile() warn: curly braces intended?

ac0a366799 staging: r8188eu: Add _enter_critical_mutex() error handling
_enter_critical_mutex() is a simple call to mutex_lock_interruptible(),
but there is no error handling code for it.

The patch removes wrapper _enter_critical_mutex() and
adds error handling for mutex_lock_interruptible().

3e4e8e025c staging: rtl8188eu: don't cast when calling rtw_set_fixed_ie()
The 'pbuf' and 'source' arguments to rtw_set_fixed_ie() are (void *), the
explicit typecasts are not needed. They just make code less readable.

Also fix checkpatch issues in the lines touched:
  ERROR: space prohibited before that ',' (ctx:WxW)
  WARNING: line over 80 characters
  CHECK: Unnecessary parentheses around <var>

Note: some of the modified lines are still over 80 characters because they
are not fixable by just adding newlines. They will be fixed in a later
patch.

0a0796eb16 staging: rtl8188eu: Introduce monitor interface for IEEE 802.11 frames
This adds support for monitoring IEEE 802.11 Data and Management frames
received or transmitted by a RTL8188EU-based device handled by this
driver.

The monitor interface is not enabled by default and will be registered
only if monitor_enable module parameter is set to 1.  When enabled it
will show up as a monX network device, which can be used by the
userspace programs for monitoring network traffic.

It is intended as an exploratory/debugging tool for rtl8188eu driver.
