[PATCH 1/2] Staging: rtl8192u: Add function to improve code quality

[Cristina Opriceana]

This patch introduces a new function for the authentication response
error check in the  ieee80211_rx_frame_softmac() function to fix the
indentation problem. It also adds the iotAction variable in the new
function to fix the "more than 80 characters per line" warning.

[PATCH 2/2] Staging: rtl8192u: Replace printk() with netdev_dbg()

[Cristina Opriceana]

This patch replaces the printk() function with netdev_dbg() in order to
fix the following: "WARNING: printk() should include KERN_ facility level"
and "WARNING: line over 80 characters".
