[PATCH 1/3] staging: rtl8192e: Avoid multiple line dereference

[Ojaswin Mujoo]

Avoid multiple line dereference to make the code more readable, as
suggested by checkpatch.pl

This patch fixes the following checkpatch.pl warning:

- WARNING: Avoid multiple line dereference
    prefer 'priv->rtllib->swcamtable[4].key_buf[0]'
  FILE: ./rtl8192e/rtl8192e/rtl_cam.c:189

    prefer 'priv->rtllib->swcamtable[4].key_buf[0]'
  FILE: ./rtl8192e/rtl8192e/rtl_cam.c:195

- WARNING: Avoid multiple line dereference
    prefer 'priv->rtllib->swcamtable[4].key_buf[0]'
  FILE: ./rtl8192e/rtl8192e/rtl_cam.c:204

- WARNING: Avoid multiple line dereference
    prefer 'priv->rtllib->swcamtable[4].key_buf[0]'
  FILE: ./rtl8192e/rtl8192e/rtl_cam.c:209

- WARNING: Avoid multiple line dereference
    prefer 'info_element->data[info_element->len]'
  FILE: ./rtl8192e/rtllib_rx.c:2287

These changes cause some of the lines to cross 80 characters however I
believe that they improve the readability and provide a good trade off.
Would love to hear your thoughts and suggestions on this.
