If anyone has any objections, please let me know. ------------------ From: Nava kishore Manne commit 6cb22477929489a412df8d153e550e77a012e701 upstream. The L0_TX_DIG_61 register bit 2 is a reserved read-only field. The previous mask value 0x0f incorrectly included bit 2, causing unintended writes to a reserved bit on every scrambler bypass operation. Correct the mask to (BIT(3) | GENMASK(1, 0)) to cover only the valid scramble bypass control bits.
