Subject: [PATCH V2] staging: r8188eu: Fix crash caused by commit 99aded71b52c

Commit 99aded71b52cfdfa22721c42e42efdd13a02f0a6 ("Staging: drivers: rtl8188eu:
use sizeof(*ptr) instead of sizeof(struct)") introduces an error in that the
sizeof(struct hal_data_8188e) is 18712, while the sizeof(*adapt->HalData) is
only 1! As a result, the system panics.

Fixes: 99aded71b52cfdfa22721c42e42efdd13a02f0a6 ("Staging: drivers: rtl8188eu: use sizeof(*ptr) instead of sizeof(struct)")
