Subject: [media] stk1160: Check return value of stk1160_read_reg() in stk1160_i2c_read_reg()
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=7c72e19dcf7f9a49eedab328ebf7c0a45d76716d;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

[media] stk1160: Check return value of stk1160_read_reg() in stk1160_i2c_read_reg()

Remember to collect the exit status from 'stk1160_read_reg()' in 'rc'
before testing it for less than zero.
