Subject: [PATCH] staging: fbtft: Changed calls to udelays() functions for usleep_range()
Date: Sun, 22 Sep 2024 09:12:13 -0300 [thread overview]
Message-ID: <20240922121213.4260-1-joakobar2000@gmail.com> (raw)
Replaced two lines of calling udelays by usleep_range() functions, adding
more efficiency due to the need of long-lasting delays of more than 10us.
