From: Shubhrajyoti Datta Date: Wed, 17 Jun 2015 15:18:14 +0000 (+0530) Subject: i2c: xiic: Remove the disabling of interrupts X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e6c9a037bc8afdce055a2a23bb61903b3844dfda;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git i2c: xiic: Remove the disabling of interrupts Currently before every transfer the interrupts are disabled. So incase the slave nacks in the middle of the transfer the current transfer is not aborted. Upon enabling the interrupts conditions like NACK , arbitration lost will not be masked. Remove the disabling of the interrupts.
