[PATCH][v2] mfd: omap-usb-tll: fix cppcheck sizeof warning

From: Colin King
Date: Tue Feb 11 2014 - 04:39:05 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Static analysis from cppcheck issued the following warning:

[drivers/mfd/omap-usb-tll.c:255]: (warning) Found calculation
inside sizeof().

The current size calculation is not obvious and is easy to
miscomprehend, so re-work the size of the allocation based
on the size of the struct pointer and quantity to allocate.
