[PATCH 1/2] i2c: xiic: Relocate xiic_i2c_runtime_suspend and xiic_i2c_runtime_resume to facilitate atomic mode

From: Manikanta Guntupalli
Date: Fri Oct 11 2024 - 06:42:10 EST


Relocate xiic_i2c_runtime_suspend and xiic_i2c_runtime_resume functions
to avoid prototype statements in atomic mode changes.
