Subject[PATCH v2 14/18] staging: rtl8188eu: simplify rtl88eu_phy_iq_calibrate
Date
The boolean is2t variable in rtl88eu_phy_iq_calibrate is always false.
Remove some code that's unused in this case.

Signed-off-by: Martin Kaiser <martin@kaiser.cx>
---
v2:
- fixed two -Wunused-but-set-variable warnings
reported by kernel test robot <lkp@intel.com>
