[PATCH v2 0/7] staging: r8188eu: clean up struct hal_data_8188e

[Michael Straube]

This series removes unused and set but never used fields from the
hal_data_8188e structure.

Tested on x86_64 with Inter-Tech DMG-02.

v2:
- Remove interrupt_handler_8188eu() since it does nothing now.
- Fixed typo in cover letter. hal_data_r8188e -> hal_data_8188e

Michael Straube (7):

[PATCH v2 1/7] staging: r8188eu: bRDGEnable is always false

[Michael Straube]

The field bRDGEnable in struct hal_data_8188e is never set. It stays
at its default value 0. Remove bRDGEnable and related dead code.

[PATCH v2 6/7] staging: r8188eu: IntArray and C2hArray are set but never used

[Michael Straube]

The fields IntArray and C2hArray of struct hal_data_8188e are set but
never used. Remove them and remove interrupt_handler_8188eu() since it
does nothing now.

While at it, remove the unsed defines USB_INTR_CONTENT_CPWM1_OFFSET
and USB_INTR_CONTENT_CPWM2_OFFSET as well.

I just noticed that INTERRUPT_MSG_FORMAT_LEN can be removed from
rtl8188e_recv.h now too. I'll send v3 soon.
