Subject: gpio: tangier: calculate number of ctx using temporary variable
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3b8d8ccc39942cb4eced890c9776567b1e4117eb;p=linux.git

gpio: tangier: calculate number of ctx using temporary variable

Utilize a temporary variable to calculate number of ctx from ngpio
inside ->probe() implementation.
While at it, include math.h for using DIV_ROUND_UP().
