Subject: [PATCH 0/7] Fix divide errors in fbdev drivers
Date: Mon,  4 Apr 2022 16:47:16 +0800	[thread overview]
Message-ID: <20220404084723.79089-1-zheyuma97@gmail.com> (raw)

None of these framebuffer drivers checks for 'pixclock', leading to many
divide errors, which we fix by checking the value of 'pixclock' in
*_check_var(). As discussed before, it is better to keep the check per
driver rather than in the caller.
