Subject: [PATCH v2 0/2] i2c: tegra: fix error handling in tegra_i2c_xfer()
Date: Thu, 7 May 2026 22:11:43 +0000	[thread overview]
Message-ID: <20260507221145.62183-1-sauravsc@amazon.com> (raw)
In-Reply-To: <20260506195319.44810-1-sauravsc@amazon.com>

Fix two bugs in the SW mutex path introduced by commit 6077cfd716fb
("i2c: tegra: Add support for SW mutex register"):

1/2: Fix pm_runtime reference leak when tegra_i2c_mutex_lock() fails.
2/2: Make tegra_i2c_mutex_unlock() return void with WARN to avoid
     silently losing transfer errors.

Changes since v1:
- Split into two patches (Jon)
- Make tegra_i2c_mutex_unlock() return void with WARN instead of
  propagating the error value (Jon)

v1: https://lore.kernel.org/all/20260506195319.44810-1-sauravsc@amazon.com/

Saurav Sachidanand (2):
  i2c: tegra: fix pm_runtime leak on mutex_lock failure
  i2c: tegra: make tegra_i2c_mutex_unlock() return void
