rtw_mlme_old.o - Previously produced object file before making any
changes to the source code.
rtw_mlme.o - Object file produced after compiling the changes done in source
file.

Following is the output of diff between the previously produced object
file and the object file produced after compiling the changes.

shreeya@Shreeya-Patel:~git/kernels/staging/drivers/staging/rtl8188eu/core$ diff rtw_mlme_old.o rtw_mlme.o
shreeya@Shreeya-Patel:~git/kernels/staging/drivers/staging/rtl8188eu/core$

Following output shows that there was no other change in the source
code except for whitespace.

shreeya@Shreeya-Patel:~git/kernels/staging$ git diff -w drivers/staging/rtl8188eu/core/
shreeya@Shreeya-Patel:~git/kernels/staging$

Changes in v2
  - Include the file name in Subject to make it more specific.
  - Add the output of diff between the previously produced object
file and the object file produced after compiling the changes.
  - Add the output of git diff -w to show no changes in source file
except for whitespace.
